Comparative Studies on a New Brackish WaterEuplotes, E. parawoodruffin. sp., and a Redescription ofEuplotes woodruffiGaw, 1939 (Ciliophora; Hypotrichida)

2012-02-05T05:31:31+00:00

Publication year: 1997Source: Archiv für Protistenkunde, Volume 148, Issue 4, December 1997, Pages 399-412Weibo Song, Phyllis C. BradburyThe morphology, nuclear apparatus, infraciliature, and silverline system of two populations of theEuplotes woodruffi-complex, one from brackish water off Pamlico Sound, North Carolina (USA), and the other from a freshwater pond in Qingdao (P.R. China), have been examined in vivo and with silver nitrate and protargol impregnations. A comparison of the two forms reveals marked differences in structure sufficient to separate the two morphotypes into two species.Euplotes parawoodruffin. sp. (syngen 1 ofE. woodruffi) is characterized by a strongly arched dorsum, regular double-eurystomastype silverline system, an adoral zone of ca. 80 membranelles extending over 4/5 of the cell length; 9 frontoventral, 2 marginal, and 2 caudal cirri; marine/brackish biotope; macronucleus irregularly T-shaped. Its T-shaped macronucleus with a short right arm differs from that ofE. woodruffi, in which the right arm is longer than the left. The general body shape ofE. parawoodruffi, broad anteriorly and tapering posteriad, differs from the ovoid shape ofE. woodruffi. Its domed dorsum without longitudinal grooves differs from the flattened dorsum with shallow grooves ofE. woodruffi. The presence of a longer AZM formed of consistently more membranelles and the absence of a pre-oral pouch (an invagination on the dorsal wall of the buccal field anterior to the cytostome, always present inE. woodruffi) further separatesE. parawoodruffifrom the latter.

SmirnovTwo new species of marine amoebae, isolated from the Sound (Denmark) are described. Comparison ofKorotnevella nivon. sp. with other known species of this genus indicated that it is difficult to use the structure of surface scales in Paramoebidae as a taxonomic character. One of the characteristic features ofHartmannella lobiferan. sp. is its remarkable cyst structure.

Publication year: 1997Source: Archiv für Protistenkunde, Volume 147, Issues 3–4, April 1997, Pages 277-282Stefanie F. KühnRhizamoeba schnepfiiwas isolated in September 1994 in plankton samples from the German Bight, North Sea. It was an obligate algivorous amoeba with an unusual feeding mode. Host diatoms were not engulfed, butR. schnepfiipierced a pseudopodium into the frustule and gradually phagocytized the diatom protoplast. The host range was tested. Observation on the feeding success revealed that some diatom species could not be consumed unless the frustule was damaged. It is discussed whether the frustule might serve as a defence mechanism against attacks by invasive protozoans.

Publication year: 1997Source: Archiv für Protistenkunde, Volume 148, Issue 4, December 1997, Pages 461-478Flemming Ekelund, David J. PattersonThe flagellates of an Australian garden soil were studied by placing coverslips on wet soil and subsequently examining the coverslips by light microscopy. A number of genera and species were found which have not previously been reported from soil samples. Besides the three new species,Apusomonas australiensissp. nov.,Peltomonas hanelisp. nov., andSciviamonas terricolagen. nov. sp. nov. they include species from the generaAmastigomonas, Cryptaulax, Paraphysomonas, andProtaspis. Among genera which have been reported from soils, we recorded a number of species previously unreported from soils:Petalomonas pusilla, Bicosoeca epiphytica, Bicosoeca mignotii, andAncyromonas sigmoides. In addition, we extracted a number of forms which have been found in soil but which are usually not considered as members of the soil flagellate community. They are:Codosiga botrytis, Salpingoeca amphoridium, andGoniomonas truncata. Only a minority of the taxa recorded are thought of as common and widespread in soils, they include:Apusomonas proboscidea, and species ofCercomonasandSpumella. At least part of the difference between communities of flagellates from freshwaters and those of soils are due to different sampling methods and not only to the existence of different communities.

Komagataella populi sp. nov. and Komagataella ulmi sp. nov., two new methanol assimilating yeasts from exudates of deciduous trees. Antonie Van Leeuwenhoek. 2012 Feb 3; Authors: Kurtzman CP Abstract Two new species of the methanol assimilating ascosporic yeast genus Komagataella are described. Komagataella populi sp. nov. (NRRL YB-455, CBS 12362, type strain, MycoBank accession number = 564110) was isolated from an exudate on a cottonwood tree (Populus deltoides), Peoria, Illinois, USA, and Komagataella ulmi sp. nov. (NRRL YB-407, CBS 12361, type strain, MycoBank accession number = 564111) was isolated from the exudate on an elm tree (Ulmus americana), also growing in Peoria, Illinois. The species were resolved from divergence in gene sequences for domains D1/D2 LSU rRNA, ITS1-5.8S-ITS2, mitochondrial small subunit rRNA, RNA polymerase subunit 1 and translation elongation factor-1α. Species of Komagataella assimilate few carbon compounds and are unlikely to be resolved from differences in standard growth and fermentation tests. For this reason, separation of species is dependent on gene sequence analysis. PMID: 22302468 [PubMed - as supplied by publisher]

Hydrocarbon-utilizing bacteria associated with biofouling materials from offshore waters of the Arabian Gulf

2012-02-05T05:31:02+00:00

Publication year: 2012Source: International Biodeterioration & Biodegradation, Volume 69, April 2012, Pages 10-16H. Al-Awadhi, N. Dashti, M. Kansour, N. Sorkhoh, S. RadwanBiofouling materials from 30 offshore substrates in eight sites along the Kuwaiti coast harbored 3 × 10–28 × 10bacterial cells g, as counted microscopically. Using culture-based methods, 7 × 10–4.1 × 10colony forming units (CFU's) were counted on a nitrogen-containing mineral medium with oil vapor as a sole carbon source. According to their 16S rDNA sequences, those bacteria were affiliated with species belonging to the generaAlcanivorax, Dietzia, Gordonia, Hoyosella, Kocuria, Marinobacter, Micrococcus, Mycobacterium, Planococcus, Planomicrobium, Pseudoalteromonas, Salinivibrio, and Vibrio. Similar numbers of CFUs appeared on the nitrogen-free mineral media; the predominant species were affiliated with most of the genera recorded above, in addition toAgrobacterium, Labrenzia, Microbacterium, Nitratireductor, Pseudomonas, and Rhodococcus. Isolates of these bacteria grew on a wide range of individual alkanes, phenanthrene, naphthalene, and biphenyl as sole carbon sources. Quantitative determinations showed that individual bacteria could attenuate crude oil, puren-octadecane, and pure naphthalene in batch cultures. Also microbial consortia associated with fresh environmental samples attenuated oil in batch cultures in the presence and absence of NaNO3. It was concluded that bacteria associated with biofouling materials probably contribute to hydrocarbon bioremediation in the Arabian Gulf.Highlights► Marine biofouling materials harbored hydrocarbon-utilizing bacteria. ► Predominant genera:Alcanivorax, Dietzia, Gordonia, Hoyosella, Pseudoalteromonas. ► Most of the isolates were also diazotrophic. ► Inoculation with biofouling materials attenuated hydrocarbons in culture.

Extremophiles. 2012 Feb 2; Authors: Schmidt M, Priemé A, Johansen A, Stougaard P Abstract Three novel Gram-positive, endospore-forming bacteria were isolated from a cold and alkaline environment. Phylogenetic analysis showed that the strains were almost identical, and that they were related to Natronobacillus azotifigens 24KS-1(T) (95.8% identity), Paraliobacillus quinghaiensis YIM-C158(T) (95.1%), Paraliobacillus ryukyuensis O15-7(T) (94.5%), and Halolactibacillus miurensis M23-1(T) (93.9%). The isolates produced amylase, α-galactosidase, β-galactosidase, and β-glucuronidase, and showed optimal growth at pH 10, at 20°C, and at 2-8% (w/v) NaCl. Major fatty acids were C(14:0) (10.6-11.6%), anteiso-C(15:0) (25.7-32.7%), C(16:1) ω11c (12.2-16.0%), and C(16:0) (14.0-20.4%). The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol, and meso-diaminopimelic acid was found in the cell-wall peptidoglycan. The G+C content was 38.4%. DNA-DNA hybridization between strain GCM68(T) and H. miurensis M23-1(T) was 32.4%, while hybridization to N. azotifigens 24KS-1(T), Amphibacillus tropicus Z-7792(T), and Paraliobacillus ryukyuensis O15-7(T) was below 30%. The phylogenetic analysis and G+C content place strain GCM68(T) in relation to species belonging to Bacillus rRNA group 1, but phylogenetic and physiologic data combined with chemotaxonomic analyses support our proposal for a new genus, Alkalilactibacillus, gen. nov., with the novel species Alkalilactibacillus ikkensis, sp. nov. (type strain is GCM68(T) = DSM 19937 = LMG 24405). PMID: 22297696 [PubMed - as supplied by publisher]

Anaerobic utilization of pectinous substrates at extremely haloalkaline conditions by Natranaerovirga pectinivora gen. nov., sp. nov., and Natranaerovirga hydrolytica sp. nov., isolated from hypersaline soda lakes. Extremophiles. 2012 Feb 1; Authors: Sorokin DY, Tourova TP, Panteleeva AN, Kaparullina EN, Muyzer G Abstract Anaerobic enrichments at pH 10, with pectin and polygalacturonates as substrates and inoculated with samples of sediments of hypersaline soda lakes from the Kulunda Steppe (Altai, Russia) demonstrated the potential for microbial pectin degradation up to soda-saturating conditions. The enrichments resulted in the isolation of six strains of obligately anaerobic fermentative bacteria, which represented a novel deep lineage within the order Clostridiales loosely associated with the family Lachnospiraceae. The isolates were rod-shaped and formed terminal round endospores. One of the striking features of the novel group is a very narrow substrate spectrum for growth, restricted to galacturonic acid and its polymers (e.g. pectin). Acetate and formate were the final fermentation products. Growth was possible in a pH range from 8 to 10.5, with an optimum at pH 9.5-10, and in a salinity range from 0.2 to 3.5 M Na(+). On the basis of unique phenotypic properties and distinct phylogeny, the pectinolytic isolates are proposed to be assigned to a new genus Natranaerovirga with two species N. hydrolytica (APP2(T)=DSM24176(T)=UNIQEM U806(T)) and N. pectinivora (AP3(T)=DSM24629(T)=UNIQEM U805(T)).

Halophilanema prolata n. gen., n. sp. (Nematoda: Allantonematidae), a parasite of the intertidal bug, Saldula laticollis (Reuter)(Hemiptera: Saldidae) on the Oregon coast. Parasit Vectors. 2012 Feb 1;5(1):24 Authors: Poinar GO Abstract ABSTRACT: BACKGROUND: It is rare to find terrestrial nematode lineages parasitizing arthropods inhabiting the intertidal or littoral zone of the oceans. During an ecological study along the Oregon dunes, an allantonematid nematode (Tylenchomorpha: Allantonematidae) was discovered parasitizing the intertidal shore bug, Saldula laticollis (Reuter)(Hemiptera: Saldidae). This shore bug is adapted to an intertidal environment and can survive short periods of submergence during high tides. The present study describes the nematode parasite and discusses aspects of its development, ecology and evolution. METHODS: Adults and last instar nymphs of S. laticollis (Hemiptera: Saldidae) were collected from the high intertidal zone among clumps of Juncus L. (Juncaceae) plants at Waldport, Oregon on October 3, 2011. The bugs were dissected in 1% saline solution and the nematodes killed in 1% Ringers solution and immediately fixed in 5% formalin (at 20o C). Third stage juveniles removed from infected hosts were maintained in 1% saline solution until they matured to the adult stage, molted and mated. RESULTS: Halophilanema prolata n. gen., n. sp. (Nematoda: Allantonematidae) is described from last instar nymphs and adults of the intertidal bug, Saldula laticollis on the Oregon coast. The new genus can be distinguished from other genera in the Allantonematidae by a stylet lacking basal knobs in both sexes, an excretory pore located behind the nerve ring, ribbed spicules, a gubernaculum, the absence of a bursa and the elongate-tubular shape of the ovoviviparous parasitic females. Studies of the organogenesis of Halophilanema showed development to third stage juveniles in the uterus of parasitic females. Maturation to the free-living adults and mating occurred in the environment. The incidence of infection of S. laticollis ranged from 0 % to 85% depending on the microhabitat in the intertidal zone. CONCLUSIONS: Based on the habitat and morphological characters, it is proposed that Halophilanema adapted a parasitic existence fairly recently, evolutionarily speaking. It was probably a free-living intertidal or shore nematode that fed on microorganisms, especially fungi, in the intertidal habitat and became parasitic after saldids entered the environment. Halophilanema represents the first described nematode parasite of an intertidal insect. PMID: 22296685 [PubMed - as supplied by publisher]

Publication year: 1992Source: Systematic and Applied Microbiology, Volume 15, Issue 3, August 1992, Pages 340-351Robert Huber, Thomas Wilharm, Dagmar Huber, Antonio Trincone, Siegfried Burggraf, ...From hot marine sediments (depth: 106 m) at the Kolbeinsey Ridge, Iceland, novel bacterial hyperthermophiles were isolated. Cells were Gram-negative highly motile rods exhibiting a complex envelope consisting of murein, an outer membrane and a surface protein layer. Growth occurred between 67 and 95 °C (opt.: 85 °C; 75 min doubling time), pH 5.4 and 7.5 (opt.: pH 6.8), and 1 to 5% NaCl (opt.: 3% NaCl). The novel isolates were strict chemolithoautotrophs. They used molecular hydrogen, thiosulfate and elemental sulfur as electron donors and oxygen (low concentrations) and nitrate as electron acceptors. During growth, sulfuric acid was formed from S° and thiosulfate. In the late logarithmic growth phase, H2S was formed from S° and H2. The core lipids consisted mainly of alkyl ethers of glycerol. The GC content of the DNA was 40 mol%. By 16S rRNA comparisons, the new isolates did not belong to any of the phyla known and represent the deepest phylogenetic branch-off within the Bacteria domain. Based on the physiological and molecular properties of the new isolates, we describe here a new genus, which we nameAquifex(the “water-maker”). The type species isAquifex pyrophilus(type strain: Kol5a; DSM 6858).

In contrast to the other species of acetic acid bacteria, the isolated strains from industrial vinegar fermenters need acetic acid for growth. They could be cultivated on a special double layer agar with 4 to 8% acetic acid (Entaniet al., 1985). DNA-DNA hybridization between the DNA of 10 isolatedA. europaeusstrains as labelled DNA probe with the type strains ofAcetobacter aceti, A. hansenii, A. liquefaciens, A. methanolicus, A. pasteurianus, A. xylinum, Gluconobacter oxydansandG. oxydanssubsp.melanogenesindicated less than 25% DNA similarity.

Molar % G+C composition and a relative heteroduplex formation of 7% with the type strain ofM. reukaufiirevealed that they did not belong to the same taxon. Comparisons with the type strain ofCandida reukaufii(CBS 1903) and the authentic strain ofNectaromyces reukaufii(CBS 611) showed no similarity with the former (22% reassociation) and conspecificity with the latter (97% reassociation). Low nuclear DNA reassociation values with all the type strains of otherMetschnikowiaspecies provided sufficient evidence for proposing a novel species,Metschnikowia gruessiithat represents the teleomorph ofNectaromyces reukaufiibut not ofCandida reukaufii. It differs from the type strain ofM. reukaufiiin its cell and ascus morphology, assimilation of trehalose and maximum temperature for growth, and from the other describedMetschnikowiaspecies by additional characteristics.

Osipov, ...Four strains of new moderately halophilic, Gram-negative anaerobic saccharolytic bacteria were isolated from Lake Sivash and its lagoons on Arabat Strait (eastern Crimea, USSR). The cells are non-sporeforming, motile rods 0.5-0.7 × 1-1.5 μm, that occur single or in pairs. Carbohydrates (preferably disaccharides, such as sucrose and trehalose) but not amino acids serve as energy sources. The end products of glucose fermentation are acetate, H2and CO2. The biomass yield is 3.8 g of protein per mol of glucose consumed. Elemental sulphur when present is reduced to H2S. All isolates are mesophiles and grow at salt concentrations from 3 to 30% NaCl (w/v) and at a pH range from 6.0 to 8.0. Doubling time of strain Z-7787 at optimal conditions (37°C., 10% NaCl, pH 7.5) is 3.9 h. The G+C content of this isolate is 31.3 mol%; that of the other strains varies from 30 to 33 mol%. All the isolates appear to be members of the same taxon but according to 5S rRNA sequencing do not belong to the genusHalobacteroides. They are considered to represent a new genus for which the nameHaloincolais proposed withHaloincola saccharolyticaas the type species. The type strain is Z-7787, DSM 6643. The taxonomic relationships ofH. saccharolyticato other haloanaerobes of the family Haloanaerobiaceae is discussed.

Publication year: 1992Source: Systematic and Applied Microbiology, Volume 15, Issue 1, February 1992, Pages 47-51A. Fonseca, J.P. SampaioThree strains of an undescribed basidiomycetous yeast, for which the nameRhodosporidium lusitaniaeis proposed, were isolated from different substrates using either protocatechuic acid or vanillic acid as the sole source of carbon and energy in the isolation medium. They showed identical morphological, physiological and biochemical properties and shared the following characteristics: absence of ballistospores, production of carotenoid pigments, homothallic production of teliospores, formation of phragmo-metabasidia and failure to grow with inositol as sole source of carbon. This led us to classify them in the genusRhodosporidiumBanno. The new strains have some phenotypic similarity with the speciesRhodosporidium dacryoidum. The molar G+C content of nDNA of the new strains is identical to the value determined for the type strain ofRo. dacryoidumbut their nDNAs showed no hybridization indicating lack of conspecificity.

Publication year: 1992Source: Systematic and Applied Microbiology, Volume 15, Issue 1, February 1992, Pages 52-58Pierre Hethener, Alain Brauman, Jean-Louis GarciaAn anaerobic, mesophilic, spore-forming, cellulolytic bacterium was isolated from the gut of a wood-feeding termite,Nasutitermes lujae. The cells were Gram-positive rods, motile by peritrichous flagella, and formed oval terminal spores which swelled the cells. The deep colonies were circular, punctiform and slightly yellow; the surface colonies spread rapidly and were diffuse. Cellulose, cellobiose, glucose, fructose, galactose, lactose, mannose, ribose, sorbose, xylose, maltose, melibiose, mannitol and sorbitol served as carbon source; glycerol was poorly used. The fermentation products were acetate, ethanol, H2, CO2. Optimal growth occurred at 37 °C and at pH 7.5. The deoxyribonucleic acid composition was 39.2 mol% guanine plus cytosine. The nameClostridium termitidissp.nov. is proposed. The type strain is strain CT1112(= DSM5398).

Dentirumai philippinensis n. gen., n. sp. (Nematoda: Philometridae), a new tissue-infecting philometrid nematode from the loach goby Rhyacichthys aspro (Valenciennes) (Rhyacichthyidae) in the Philippines. J Helminthol. 2012 Jan 31;:1-7 Authors: Quiazon KM, Moravec F Abstract A new genus and species of the philometrid nematode Dentirumai philippinensis n. gen., n. sp. Philometrinae, Philometridae, are described on the basis of the female specimens found in the loach goby, Rhyacichthys aspro (Valenciennes), from the upper Bianuan River, Municipality of Casiguran, Aurora Province, in the Philippine Archipelago. Dentirumai philippinensis was collected from the body cavity, subcutaneous tissues near the bases of the pectoral and pelvic fins, and surrounding body tissues in the hypaxial musculature of R. aspro. Based on light microscopic and scanning electron microscopic examination, the new nematode species is morphologically close to the genus Rumai Travassos, 1960 except for one major difference, i.e. the presence of a sclerotized ring in the oral aperture armed with distinct numerous minute teeth on its inner surface. This important taxonomic feature makes it possible to erect a new genus, Dentirumai n. gen. to accommodate the newly discovered philometrid species. A key to genera of the Philometrinae is provided.

Micromonospora cremea sp. nov. and Micromonospora zamorensis sp. nov., isolated from the rhizosphere of Pisum sativum. Int J Syst Evol Microbiol. 2012 Jan 27; Authors: Carro L, Pukall R, Spröer C, Kroppenstedt RM, Trujillo ME Abstract Three actinobacterial strains, CR30T, CR36 and CR38T were isolated from the rhizosphere soil of Pisum sativum plants collected in Spain. The strains were filamentous, Gram-positive and produced single spores. Phylogenetic, chemotaxonomic and morphological analyses confirmed that the three strains belonged to the genus Micromonospora. 16S rRNA gene sequences of strains CR30T and CR36 showed closest relationship with Micromonospora coriariae NAR01T (99.3% similarity) while strain CR38T had a similarity of 99.0% with Micromonospora saelicesensis Lupac 09T. In addition, gyrB gene phylogeny clearly differentiated the new isolates from established Micromonospora species. DNA-DNA hybridization, BOX PCR and ARDRA profiles confirmed that these strains represent new genomic species. The cell-wall peptidoglycan of strains CR30T and CR38T contained meso-DAP. Both strains had MK-10(H4) as the main menaquinone and a phospholipid type II pattern. An array of physiological tests also differentiated the new isolates from their closest neighbours. Considering all the data obtained, it is proposed that strains CR30T and CR36 represent a new species under the name Micromonospora cremea sp. nov. (type strain CR30T = CECT 7891T = DSM 45599T), while the name Micromonospora zamorensis sp. nov. is proposed with isolate CR38T (= CECT 7892T = DSM 45600T) as the type strain.

Paracoccus rhizosphaerae sp. nov., a novel species isolated from the rhizosphere of a plant Crossostephium chinense (L.) Makino (Seremban). Int J Syst Evol Microbiol. 2012 Jan 27; Authors: Kämpfer P, Lai WA, Arun AB, Young CC, Rekha PD, Martin K, Busse HJ, Chen WM Abstract A Gram-negative organism producing coccoid cells (CC-CCM15-8T) isolated from a rhizosphere soil sample of the plant Crossostephium chinense (L.) Makino (Seremban) from Budai Township, Chiayi County, Taiwan was taxonomically studied. 16S rRNA gene sequence analysis indicated a clear allocation of the isolate CC-M15-8T to the Paracoccus cluster, showing the highest similarities to the type strains of Paracoccus beibuensis (98.8%), Paracoccus homiensis (97.6%), Paracoccus aestuarii (97.7%) and Paracoccus zeaxanthinifaciens (97.7%). The fatty acids profile comprising the major fatty acid C18:1 ω7c beside the characteristic hydroxylated fatty acid C10:0 3-OH supported the grouping of strain CC-M15-8T to the genus Paracoccus. The polyamine pattern consisted of the major components putrescine and spermidine. Ubiqinone Q10 was the major quinone type (95%) Ubiquinone Q-9 could also be detected (5%). The complex polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholin, unidentified phospholipids, lipids and two glycolipids. DNA-DNA hybridizations between CC-M15-8T and Paracoccus beibuensis LMG 25871T, Paracoccus aestuarii DSM 19484T, P. zeaxanthinifacienss LMG 21993T and P. homiensis KACC 11518T resulted in values of 24.9% (34.8%, reciprocal analysis), 15.7% (17.5%, reciprocal analysis), 17.7% (23.4%, reciprocal analysis), and 16.0%, respectively. These data as well as the physiological and biochemical tests allowing a phenotypic differentiation of strain CC-M15-8T from the most closely related Paracoccus species it is concluded, that CC-M15-8T represents novel species of the genus Paracoccus, for which we propose the name Paracoccus rhizosphaerae sp. nov. The type strain is CC-CCM15-8T (= LMG 26205T = CCM 7904T). PMID: 22286908 [PubMed - as supplied by publisher]

Genetically the isolates were most close to Rhodovulum steppense and Rhodovulum strictum, from which they differed at the species level (98.5 % 16S rRNA gene identity and 40-53% DNA-DNA hybridization level). According to genotypic and phenotypic characteristics, the investigated strains were assigned to a new species of the genus Rhodovulum, for which the name Rhodovulum tesquicola is proposed. Cells of both strains were ovoid to rod-shaped, 0.4-0.8 μm in width and 1-2.5 μm in length, motile by means of polar flagellum. They contained internal photosynthetic membranes of vesicular type and photosynthetic pigments (bacteriochlorophyll a and carotenoids of spheroidene series). Both strains were obligate haloalkaliphiles, growing in wide ranges of salinity (0.3-10%) and pH (7.5-10), with growth optima at 1-3 % NaCl and pH 8.5-9.0. Photo- and chemoheterotrophic growth occurred with a number of organic compounds and biotin, ρ-aminobenzoate, thiamine, and niacin as growth factors. No anaerobic respiration on nitrite, nitrate, fumarate and no fermentation was demonstrated. Bacteria grew photo- and chemolithoautotrophically with sulfide, sulfur, and thiosulfate, oxidizing them to sulfate. Sulfide was oxidized via deposition of extracellular elemental sulfur. No growth with H2 as electron donor was demonstrated. The major fatty acid was 18:1 (78 %). The major quinone was Q-10. The DNA G+C content was 65.4 mol% (Tm). The type strain A-36sT (=VKM B-2491 =ATCC BAA-1573) was isolated from steppe soda lake Sul'fatnoe (Zabaikal'skii Krai, southern Siberia, Russia). PMID: 22286907 [PubMed - as supplied by publisher]

Mycetocola manganoxydans sp. nov., novel actinobacteria isolated from the Taklamakan desert. Int J Syst Evol Microbiol. 2012 Jan 27; Authors: Luo X, Wang J, Zeng XC, Wang Y, Zhou L, Nie Y, Dai J, Fang C Abstract Two novel bacteria, which are Gram-positive, aerobic, non-sporulating, short rods to cocci-shaped, were isolated from Takalima desert. These bacteria can oxidize manganese ions. The 16S rDNA sequences of the two isolates share 95.4%-98.0% homology with the type strains of the genus Mycetocola. Although the two bacteria possess similar chemotaxonomic properties with the species M. reblochoni, they were readily distinguished from this taxon based on DNA-DNA relatedness, and phenotypic data. According to their morphological and chemotaxonomic characteristics, phylogenetic analysis and DNA hybridization results, the two novel isolates are classified into the genus Mycetocola. They represent two members of a novel species which was referred to as Mycetocola manganoxydans sp. nov. The type strain is MB1-14T (=CCTCC AB209002T= KCTC 19753T).

Legionella cardiaca sp. nov., isolated from a case of native valve endocarditis in a human heart. Int J Syst Evol Microbiol. 2012 Jan 27; Authors: Pearce MM, Theodoropoulos N, Mandel MJ, Brown E, Reed KD, Cianciotto NP Abstract A Gram-negative, rod-shaped bacterium, designated H63T, was isolated from the aortic valve tissue of a patient with native valve endocarditis. 16S rRNA sequencing revealed that H63T belongs to the genus Legionella with its closest neighbors being Legionella brunensis (98.8%), Legionella londiniensis (97.0%), Legionella jordanis (96.8%), Legionella erythra (96.2%), Legionella dresdenensis (96.0%), and Legionella rubrilucens, Legionella feeleii, Legionella pneumophila and Legionella birminghamensis (95.7%). DNA-DNA hybridization values indicated that H63T is < 70% similar to its nearest 16S rRNA neighbors, documenting that the strain is a novel species. Phylogenetic analysis of the 16S rRNA, macrophage infectivity potentiator (mip), and RNase P (rnpB) genes confirmed that H63T is a distinct species, with L. brunensis being its closest sister taxon. Fatty acid composition and biochemical traits, such as the inability to ferment glucose and reduce nitrate, supported the affiliation of H63T to the genus Legionella. H63T was distinguishable from its neighbors based on it being hippurate-hydrolysis positive and oxidase negative. H63T was further differentiated by its inability to grow on BCYE agar at 170C, poor growth on low-iron media, and lack of sliding motility. Also, H63T did not react with antisera generated from Legionella species type strains. H63T replicated within macrophages. It also grew in mouse lungs, inducing histopathologic evidence of pneumonia and dissemination to the spleen. Together, these results confirm that H63T is a novel, pathogenic Legionella species for which the name Legionella cardiaca sp. nov. (type strain H63T =ATCC BAA-2315 = DSM 25049 = JCM 17854) is proposed. PMID: 22286905 [PubMed - as supplied by publisher]

Vibrio alfacsensis sp. nov., isolated from marine organisms.

2012-02-01T17:03:14+00:00

Vibrio alfacsensis sp. nov., isolated from marine organisms. Int J Syst Evol Microbiol. 2012 Jan 27; Authors: Gomez-Gil B, Roque A, Chimetto L, Moreira AP, Thompson FL, Lang E Abstract Five strains were isolated from cultured sole (Solea senegalensis) in two regions of Spain, two strains from wild caught spotted rose snapper (Lutjanus guttatus) in Mexico, and one strain from corals in Brazil. The 16S rRNA sequences showed similarity to Vibrio ponticus (98.2-98.3 %) and to a lesser degree to Vibrio furnissii (97.2-97.3 %), and to V. fluvialis (96.9-97.1 %). MLSA clustered these strains closely together and clearly separated them from phylogenetically related Vibrio species. Genomic fingerprinting by rep-PCR clustered the strains according to their geographic origin. Phenotypic analyses showed a large variation among the strains, but many tests could differentiate them from other Vibrio species. The mean ΔTm values between the strains analyzed here and the closely related type strains were above 6.79 °C, and below 2.35 °C between these strains, well outside the limit to delineate a bacterial species. The phenotypic and genotypic data presented here, clearly place these strains as a coherent group within the Vibrio genus, for which we propose the name Vibrio alfacsensis sp. nov. CAIM 1831(T) (=DSM 24595(T)) is proposed as the type strain of the species. PMID: 22286904 [PubMed - as supplied by publisher]

Sulfur species and biosignatures in Sulphur Springs, Valles Caldera, New Mexicoâ€”Implications for Mars astrobiology

2012-02-01T17:03:14+00:00

Publication year: 2012Source: Earth and Planetary Science Letters, Volumes 321â€“322, 1 March 2012, Pages 1-13AnnaÂ Szynkiewicz, Adam P.Â Johnson, Lisa M.Â PrattA biogeochemical SO4cycle was investigated in the acid-hot springs of Valles Caldera, New Mexico using S isotopes and distribution of amino acids. In 2007, a major contribution of SO4in this modern volcanic setting came from oxidation of H2S from hydrothermal sources, which largely increased SO4concentrations (up to 2550Â mgÂ L) and decreased pH (down to 2.27) in surface water. A relatively small variation of Î´S among the analyzed S-bearing minerals (2.1 to 4.0â€°), fumarole H2S (1.7 to 4.6â€°) and dissolved SO4in modern surface and groundwater (2.5 to 7.9â€°) indicates poor evidence of S isotope biosignatures related to microbial disproportionation of elemental S to H2S and SO4which, in turn, are not effectively captured in the hydrothermal minerals of the studied volcanic setting. This is mainly due to prevailing contribution of reduced S forms from magmatic/hydrothermal sources and considerably smaller microbial activity in acid-hot spring areas. Although hydrothermal gypsum and elemental S effectively trap amino acids, their preservation lifetimes in S-bearing hydrothermal minerals appear to be small. The minimal lifetimes are inferred to be the result of increased temperatures and rapid recycling time of S materials in hydrothermal settings.Landed missions to the Martian surface at sites inferred to have experienced active hydrothermal activity similar to the one studied in Valles Caldera (e.g., elevated volcanic S flux), may provide valuable insight into geological and geochemical processes that have influenced the Martian surface, but may provide minimal potential for recording either amino acid or S isotopic biosignatures of an extinct Martian ecosystem.Highlightsâ–º Hydrothermal settings minimize preservation of S isotope and amino acid biosignatures. â–º Abiotic oxidation of magmatic H2S overprints the biotic S isotope fractionation. â–º Amino acid decarboxylation and racemization rates are rapid in hydrothermal deposits. â–º Martian hydrothermal sites may provide minimal preservation of similar biosignatures.

Two new species are described:S.Â grosdidierinov. sp. andS.Â viviersaenov. sp. The three species ofSergipellaare restricted to areas of the South Atlantic during the late Aptian-early Cenomanian. The present data provide detailed taxonomic criteria for the identification of the type-species ofSergipellaand its closely related species. A detailed analysis of the internal and external characteristics of the valves shows that the genusSergipellathat belongs to the Family Trachyleberididae, although it possesses some characteristics close to those of Protocytheridae. This study is based on samples from Riachuelo Formation, lower Albian, Sergipe/Alagoas basin, Sergipe State, NE-Brazil and from wells in West Africa, MadiÃ©la Formation, lower Albian, Gabon basin, east of Libreville, Gabon.

Molecular and phenotypic characterization of Sebacina vermifera strains associated with orchids, and the description of Piriformospora williamsii sp. nov. Fungal Biol. 2012 Feb;116(2):204-213 Authors: Basiewicz M, Weiß M, Kogel KH, Langen G, Zorn H, Zuccaro A Abstract Sebacinales was described in 2004 and is currently recognized as the earliest diverging lineage of mycorrhizal Basidiomycota. In addition, recent research has demonstrated that no other known fungal order harbours a broader spectrum of mycorrhizal types. Yet because of the character poor morphology of these inconspicuous fungi, a reliable systematic framework for Sebacinales is still out of reach. In order to increase the body of comparative data on Sebacinales, we followed a polyphasic approach using a sampling of seven diverse Sebacinales strains, including several isolates of Australian orchid mycorrhizae, Piriformospora indica, and a multinucleate rhizoctonia isolated from a pot culture of Glomus fasciculatum (Williams 1985) with clover. We performed molecular phylogenetic analyses from candidate barcoding regions [rDNA: internal transcribed spacer (ITS)1-5.8-ITS2, 28S; translation elongation factor 1-α (TEF)], enzymatic profiling, genome size estimation by quantitative polymerase chain reaction (PCR), and karyotype analysis using pulsed field gel electrophoresis. Here, we report significant differences in the physiological and molecular parameters inferred from these morphologically very similar strains. Particularly, our results indicate that intron sequences of the TEF gene are useful markers for Sebacinales at the species level. As a first taxonomic consequence, we describe Piriformospora williamsii as a new member of the so far monotypic genus Piriformospora and show that this genus contains still undescribed species that were recently discovered as endophytes of field-collected specimens of Anthyllis, Medicago, and Lolium in Germany.

A NEW MORPHOLOGICALLY DISTINCT AVIAN MALARIA PARASITE THAT FAILS DETECTION BY ESTABLISHED PCR-BASED PROTOCOLS FOR AMPLIFICATION OF THE CYTOCHROME B GENE.

A NEW MORPHOLOGICALLY DISTINCT AVIAN MALARIA PARASITE THAT FAILS DETECTION BY ESTABLISHED PCR-BASED PROTOCOLS FOR AMPLIFICATION OF THE CYTOCHROME B GENE. J Parasitol. 2012 Jan 30; Authors: Zehtindjiev P, Križanauskienė A, Bensch S, Palinauskas V, Asghar M, Dimitrov D, Scebba S, Valkiunas G Abstract Abstract Plasmodium polymorphum n. sp. (Haemosporida, Plasmodiidae) was found in the skylark Alauda arvensis (Passeriformes, Alaudidae) during autumnal migration in southern Italy. This organism is illustrated and described based on the morphology of its blood stages. The most distinctive feature of this malaria parasite is the clear preference of its blood stages (trophozoites, meronts and gametocytes) for immature red blood cells, including erythroblasts. Based on preference of erythrocytic meronts for immature red blood cells, P. polymorphum is most similar to species of the subgenus Huffia. This parasite can be readily distinguished from all other bird malaria parasites, including P. (Huffia) sp. due to preferential development and maturation of its gametocytes in immature red blood cells, a unique character for avian Plasmodium spp. Additionally, the margins of nuclei in blood stages of P. polymorphum are markedly smooth and distinct; this is also a distinct diagnostic feature of this parasite. Plasmodium polymorphum has been recorded only in the skylark; it is probably a rare parasite, whose host range and geographical distribution remain unclear. Microscopic examination detected a light infection of Plasmodium relictum (lineage GRW11, parasitemia of < 0.01%) in the same sample with P. polymorphum; the latter parasite clearly predominated (3.5% parasitemia). However, experienced researchers were unable to detect sequences of mitochondrial cytochrome b gene (cyt b) of P. polymorphum from the microscopically positive sample using published and newly designed primers for DNA amplification of avian Plasmodium spp. The light parasitemia of P. relictum was easily detectable using several PCR-based assays, but P. polymorphum was undetectable in all applied assays. Quantitative PCR also showed the presence of light parasitemia (0.06%) of the lineage GRW11 in this sample. This supports the conclusion that the morphologically distinct parasite observed along with P. relictum and predominant in the sample, is genetically dissimilar from the lineage GRW11 based on cyt b sequence. In samples with co-infections, general PCR protocols tend to favor the amplification of the parasite with the higher parasitemia or the one with the best matching sequence to the primers. Because the parasitemia of P. polymorphum was over 50-fold higher than that of P. relictum and several different primers were tested, we suggest that the failure to amplify P. polymorphum is a more complex problem than why co-infections are commonly overlooked in PCR-based studies. We suggest possible explanations of these results and call for additional research on evolution of mitochondrial genome of hemosporidian parasites. PMID: 22288487 [PubMed - as supplied by publisher]

Heterosporis schubertin.sp., a new microsporidian parasite of aquarium fish

Publication year: 1989Source: European Journal of Protistology, Volume 25, Issue 2, 27 October 1989, Pages 129-135JiÅ™ÃÂ Lom, IvaÂ DykovÃ¡, WolfgangÂ KÃ¶rting, HeinerÂ KlingerHeterosporis schubertin.sp. is described from the myocytes of an ornamental fish,Pseudocrenilabrus multicolor(Cichlidae). An apparently identical species was also found inAncistrus cirrhosus(Loricariidae). Early meronts â€” uninucleate or plurinucleate â€” are perhaps responsible for dissemination of the infection throughout the muscle tissue. Later development of the microsporidian takes place in a structure encased with a thick envelope, for which the name sporophorocyst is proposed. At first, it contains merogony stages. Later, sporogony stages appear, too, which eventually prevail until a voluminous sporophorocyst is packed full with sporophorous vesicles with macrospores and rather rare microspores.Pleistophora anguillarumreveals features similar enough to permit its reassignment to the genusHeterosporis.

Sipunculan phylogeny based on six genes, with a new classification and the descriptions of two new families

2012-01-31T10:56:10+00:00

Kawauchi, G. Y., Sharma, P. P. & Giribet, G. (2012). Sipunculan phylogeny based on six genes, with a new classification and the descriptions of two new families. â€”Zoologica Scripta, 00, 000â€“000.The internal phylogeny of Sipuncula has proven elusive, with the monophyly of multiple traditional groups in question. Repeated attempts to infer sipunculan relationships have attained discordant results, possibly owing to fragmentary molecular sequence data sets. We reassessed the phylogeny of Sipuncula using a sixâ€gene data set and with larger target amplicons of certain loci. We additionally dated the molecular phylogeny employing recently discovered fossil taxa to constrain node ages. Our multilocus data set recovers six major clades of Sipuncula across multiple analytical treatments. Some groups considered suspect in previous studies are vindicated (e.g. Aspidosiphonidae), but most traditional sipunculan families were recovered as paraâ€ or polyphyletic groups, especially Sipunculidae, whose members appear in three distinct clades. To redress the dissonance between the current classification and the phylogeny of Sipuncula, we provide a new classification of the group, wherein (i) we erect two new families, Siphonosomatidae fam. nov. and Antillesomatidae fam. nov.; (ii) Phascolionidae and Themistidae are synonymized with Golfingiidae, new synonymies (iii) Phascolopsis is transferred to Golfingiidae, new familial assignment; and (iv) Lithacrosiphon is synonymized with Aspidosiphon, new synonymy. We observe that the origins of all families recognized are ancient, dating at least to the Mesozoic.

Mature spores are cylindrical, with a short tail-like projection of exospore material. The spore wall has a uniform exospore. The polaroplast has two regions, anteriorly with closely packed lamellae, posteriorly with tubules. The polar filament has a wide, straight anterior portion, and an approximately equally long, narrow posterior section, forming one coil. Each spore is enclosed in a double-layered sac-like structure, formed by the sporoblast from exospore material. The identity of the species and some traits on the ultrastructural cytology are discussed.

Publication year: 1988Source: Systematic and Applied Microbiology, Volume 10, Issue 3, August 1988, Pages 273-278G.Â Dietrich, N.Â Weiss, F.Â Fiedler, J.Â WinterA new, strictly anaerobic, non-sporeforming, non-motile, rigid, long filaments forming bacterium, strain MN, was isolated from a sewage sludge fermenter. Cells stained Gram-negative. Single cells were extremely thin, 0.18â€“0.3 Ã— 2â€“3Î¼m in size. Filaments of more than 100 Î¼m in length were frequently formed. Optimum growth was between 35â€“38Â°C, optimum pH between 7.3â€“8.5. Growth was dependent on the presence of yeast extract. Acetate and H2in a molar ratio of 1:2 as well as CO2were formed from hexoses. Increasing hydrogen partial pressure inhibited growth, while elevated acetate concentration did not affect growth of strain MN.The G+C content of the DNA was 47 mol%. The new mesophilic isolate was namedAcetofilamentum rigidumgen. nov., sp. nov. with isolate MN, deposited in the Deutsche Sammlung fÃ¼r Mikroorganismen under DSM 20769, as the type strain.

Publication year: 1988Source: Systematic and Applied Microbiology, Volume 10, Issue 3, August 1988, Pages 279-283R.Â Beck, N.Â Weiss, J.Â WinterA group of 11 facultatively heterofermentative rod-shaped bacteria were isolated at a late fermentation stage of pre-wilted grass. These bacteria were found to differ from currently described lactobacilli in the spectrum of fermented sugars, in particular in their ability to ferment xylose. The isolates were similar toLactobacillus curvatusandLactobacillus sakewith respect to D(-)- and L(+)- lactate formation, Rf-values of the D- and L-LDH, G+C content of the DNA and the L-Lys-D-Asp murein type. Teichoic acid was lacking. DNA-DNA homology among the isolates was high, while low homology values were obtained with the type strains ofL. curvatusandL. sake, indicating only a distant relationship. It is proposed that the isolates represent a new species namedLactobacillus graminissp. nov.

Publication year: 1988Source: Systematic and Applied Microbiology, Volume 10, Issue 3, August 1988, Pages 284-292PierreÂ Caumette, RenÃ©eÂ Baulaigue, RobertÂ MatheronIn the course of ecological studies in salinas and salt-works of Salin de Giraud (Camargue, France), a halophilic strain of theChromatiaceaewas isolated from a red layer below the gypsum crust. Because of its morphology, this strain (SG 3201) was assigned to the genusChromatium, resemblingChromatium buderiandChromatium vinosum. However it differed from these species in some physiological characteristics, in particular pigment composition, salinity range with 10% NaCl requirement for optimum growth, and utilization of some substrates. It is the first describedChromatiumstrain with high NaCl requirement. Therefore, a new species,Chromatium salexigens, is proposed.

The Phylogeny of the Genus Clostridium: Proposal of Five New Genera and Eleven New Species Combinations

2012-01-30T08:07:49+00:00

International Journal of Systematic Bacteriology, Vol. 44, No. 4. (01 October 1994), pp. 812-826.The 16S rRNA gene sequences of 34 named and unnamed clostridial strains were determined by PCR direct sequencing and were compared with more than 80 previously determined clostridial sequences and the previously published sequences of representative species of other low- G+C-content gram-positive genera, thereby providing an almost complete picture of the genealogical interrelationships of the clostridia. The results of our phylogenetic analysis corroborate and extend previous findings in showing that the genus Clostridium is extremely heterogeneous, with many species phylogenetically intermixed with other sporeforming and non-sporeforming genera. The genus Clostridium is clearly in need of major revision, and the rRNA structures defined in this and previous studies may provide a sound basis for future taxonomic restructuring. The problems and different possibilities for restructuring are discussed in light of the phenotypic and phylogenetic data, and a possible hierarchical structure for the clostridia and their close relatives is presented. On the basis of phenotypic criteria and the results of phylogenetic analyses the following five new genera and 11 new combinations are proposed: Caloramator gen. nov., with Caloramator fervidus comb. nov.; Filifactor gen. nov., with Filifactor villosus comb. nov.; Moorella gen. nov., with Moorella thermoacetica comb. nov. and Moorella thermoautotrophica comb. nov.; Oxobacter gen. nov., with Oxobacter pfennigii comb. nov.; Oxalophagus gen. nov., with Oxalophagus oxalicus comb. nov.; Eubacterium barkeri comb. nov.; Paenibacillus durum comb. nov.; Thermoanaerobacter kivui comb. nov.; Thermoanaerobacter thermocopriae comb. nov.; and Thermoanerobacterium thermosaccharolyticum comb. nov.MD Collins, PA Lawson, A Willems, JJ Cordoba, J fernandez-Garayzabal, P Garcia, J Cai, H Hippe, JAE Farrow

Piriformospora indica, gen. et sp. nov., a New Root-Colonizing Fungus

2012-01-29T04:46:41+00:00

Mycologia, Vol. 90, No. 5. (1998), pp. 896-903.A new fungus isolate was discovered in an arbuscular mycorrhizal fungal spore from a desert soil in India. It could easily be cultivated on various synthetic media, and formed pear-shaped chlamydospores. Inoculation of maize showed that the fungus colonized the root cortex. Since it did not resemble any known fungus based on morphology and ultrastructure, a new genus was described. For its characteristic spore structure the isolate was named Piriformospora indica. Electron microscopy revealed the presence of typical dolipores with continuous parenthesomes, which indicated that P. indica belongs to the Hymenomycetes (Basidiomycota). DNA was extracted and the 5′ end of the 18S rRNA was amplified and sequenced. Comparison with sequences from the Genbank data base indicated that P. indica is related to the Rhizoctonia group.Savita Verma, Ajit Varma, Karl Rexer, Annette Hassel, Gerhard Kost, Ashok Sarbhoy, Prakash Bisen, Britta Bütehorn, Philipp Franken

Microbacterium marinum sp. nov., isolated from deep-sea water.

2012-01-29T04:46:35+00:00

Microbacterium marinum sp. nov., isolated from deep-sea water. Syst Appl Microbiol. 2012 Jan 24; Authors: Zhang L, Xi L, Ruan J, Huang Y Abstract Two Gram-positive, rod-shaped bacterial strains, H101(T) and H207, were isolated from deep sea water collected from South-West Indian Ocean. Phylogenetic analysis of 16S rRNA gene sequences showed that the two strains were closely related to one another (100% similarity), and had the closest relationship with Microbacterium hominis NBRC 15708(T) and Microbacterium insulae KCTC 19247(T) (98.2-98.3% similarities). DNA-DNA hybridization value between strains H101(T) and H207 was 87.2±3.7%, and the values between the two strains and the closely related type strains were well below 70%. The two strains also shared a number of physiological and biochemical characteristics that were distinct from the closely related species, and grew at 2-37°C, pH 5-11 and 0-8% (w/v) NaCl. Both strains contained MK-12, MK-13 and MK-11 as the detected menaquinones. The peptidoglycan was of type B1γ with an interpeptide bridge D-Glu(Hyg)→Gly(2)→l-Lys. The major cellular fatty acids were anteiso-C(15:0), anteiso-C(17:0), and iso-C(16:0). Based on the genetic and phenotypic properties, it is proposed that strains H101(T) and H207 be classified as representatives of a novel species of the genus Microbacterium, with the name Microbacterium marinum sp. nov. The type strain is H101(T) (=CGMCC 4.6941(T)=DSM 24947(T)). PMID: 22280899 [PubMed - as supplied by publisher]

Tropicibacter phthalicus sp. nov., A Phthalate-Degrading Bacterium from Seawater.

2012-01-28T04:21:10+00:00

Tropicibacter phthalicus sp. nov., A Phthalate-Degrading Bacterium from Seawater. Curr Microbiol. 2012 Jan 26; Authors: Iwaki H, Nishimura A, Hasegawa Y Abstract An aerobic, Gram-negative bacterial strain, designated KU27E1(T), which degrades phthalate and dimethylphthalate, was isolated from seawater obtained from the coastal region of Ishigaki Island, Japan. Cells are motile rods with polar flagella. Strain KU27E1(T) grew at 15-30°C, pH 6.0-8.0, in the presence of 1.0-2.0% (w/v) NaCl. The 16S rRNA gene sequence analysis revealed that this strain was affiliated with the family Rhodobacteraceae in the class Alphaproteobacteria, and was most closely related to Tropicibacter naphthalenivorans (96.8%). The predominant respiratory lipoquinone was ubiquinone-10, and the major cellular fatty acid was C(18:1)ω7c (88.5%). The G+C content of genomic DNA was 58.7 mol%. Based on the physiological, chemotaxonomic, and phylogenetic data, strain KU27E1(T) is suggested to represent a novel species of the genus Tropicibacter, for which the name Tropicibacter phthalicus sp. nov. is proposed. The type strain of Tropicibacter phthalicus is designated as KU27E1(T) (=JCM 17793(T) = KCTC 23703(T)). PMID: 22278761 [PubMed - as supplied by publisher]

Oceaniovalibus guishaninsula gen. nov., sp. nov., A Marine Bacterium of the Family Rhodobacteraceae.

2012-01-28T04:21:10+00:00

Oceaniovalibus guishaninsula gen. nov., sp. nov., A Marine Bacterium of the Family Rhodobacteraceae. Curr Microbiol. 2012 Jan 26; Authors: Liu K, Zong R, Li Q, Fu Y, Xu Y, Wang Y, Jiao N Abstract The alphaproteobacterial strain JLT2003(T) was isolated from surface seawater off the coast of Guishan island, Taiwan. The strain was Gram negative, ovoid or coccoid, non-motile and formed pink colonies on marine agar 2216 (MA; DIFCO) medium. The dominant fatty acids were C(18:1)ω7c, cyclo C(19:0)ω8c, and C(16:0). The polar lipid profile consisted of diphosphatidylglycerol and phosphatidylglycerol. The major respiratory ubiquinone was Q-10. The DNA G+C content was 62.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was most closely related to Pontibaca methylaminivorans GRP21(T) with 94.8% similarity. The isolate was distinguishable from members of the family Rhodobacteraceae based on phenotypic and biochemical characteristics. On the basis of the taxonomic data presented, strain JLT2003(T) is considered to represent a novel species of a new genus, for which the name Oceaniovalibus guishaninsula gen. nov., sp. nov. is proposed. The type strain of Oceaniovalibus guishaninsula is JLT2003(T) (=JCM 17765(T) = CGMCC 1.10827(T)). PMID: 22278760 [PubMed - as supplied by publisher]

A new stalked filter-feeder from the middle cambrian burgess shale, british columbia, Canada.

A new stalked filter-feeder from the middle cambrian burgess shale, british columbia, Canada. PLoS One. 2012;7(1):e29233 Authors: O'Brien LJ, Caron JB Abstract Burgess Shale-type deposits provide invaluable insights into the early evolution of body plans and the ecological structure of Cambrian communities, but a number of species, continue to defy phylogenetic interpretations. Here we extend this list to include a new soft-bodied animal, Siphusauctum gregarium n. gen. and n. sp., from the Tulip Beds (Campsite Cliff Shale Member, Burgess Shale Formation) of Mount Stephen (Yoho National Park, British Columbia). With 1,133 specimens collected, S. gregarium is clearly the most abundant animal from this locality.This stalked animal (reaching at least 20 cm in length), has a large ovoid calyx connected to a narrow bilayered stem and a small flattened or bulb-like holdfast. The calyx is enclosed by a flexible sheath with six small openings at the base, and a central terminal anus near the top encircled by indistinct openings. A prominent organ, represented by six radially symmetrical segments with comb-like elements, surrounds an internal body cavity with a large stomach, conical median gut and straight intestine. Siphusauctum gregarium was probably an active filter-feeder, with water passing through the calyx openings, capturing food particles with its comb-like elements. It often occurs in large assemblages on single bedding planes suggesting a gregarious lifestyle, with the animal living in high tier clusters. These were probably buried en masse more or less in-situ by rapid mud flow events.Siphusauctum gregarium resembles Dinomischus, another Cambrian enigmatic stalked animal. Principal points of comparison include a long stem with a calyx containing a visceral mass and bract-like elements, and a similar lifestyle albeit occupying different tiering levels. The presence in both animals of a digestive tract with a potential stomach and anus suggest a grade of organization within bilaterians, but relationships with extant phyla are not straightforward. Thus, the broader affinities of S. gregarium remain largely unconstrained. PMID: 22279532 [PubMed - in process]

Geodermatophilus nigrescens sp. nov., isolated from a dry-hot valley. Antonie Van Leeuwenhoek. 2012 Jan 25; Authors: Nie GX, Ming H, Li S, Zhou EM, Cheng J, Yu TT, Zhang J, Feng HG, Tang SK, Li WJ Abstract A novel actinomycete, designated as strain YIM 75980(T), was isolated from a soil sample collected from a dry-hot river valley in Dongchuan county, Yunnan province, south-west China and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, red to black coloured colonies comprising coccoid-shaped cells. Colonies on agar medium lacked mycelia and cells adhered to the agar. Strain YIM 75980(T) contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan and contained galactose, arabinose and glucosamine as the main sugars in the whole-cell hydrolysates. The predominant menaquinone was MK-9 (H(4)) and the major fatty acids were iso-C(15:0), iso-C(16:0) and C(16:0). The DNA G + C content of strain YIM 75980(T) was 73.1 mol%. Phylogenetic analyses based on 16S rRNA gene sequences clearly showed that strain YIM 75980(T) formed a distinct clade within the genus Geodermatophilus and was closely related to Geodermatophilus obscurus DSM 43160(T) (level of similarity, 97.9%). Furthermore, the result of DNA-DNA hybridization between strain YIM 75980(T) and G. obscurus 43160(T) demonstrated that this isolate represented a different genomic species in the genus Geodermatophilus. Moreover, the physiological and biochemical data showed the differentiation of strain YIM 75980(T) from its closest phylogenetic neighbour. Therefore, it is proposed that strain YIM 75980(T) represents a novel species of the genus Geodermatophilus, for which the name Geodermatophilus nigrescens sp. nov. is proposed. The type strain is YIM 75980(T) (=CCTCC AA 2011015(T) =JCM 18056(T)). PMID: 22273761 [PubMed - as supplied by publisher]

Sulfolobus metallicus, sp. nov., a Novel Strictly Chemolithoautotrophic Thermophilic Archaeal Species of Metal-Mobilizers

2012-01-25T16:46:12+00:00

Publication year: 1991Source: Systematic and Applied Microbiology, Volume 14, Issue 4, October 1991, Pages 372-378Gertrud Huber, Karl O. StetterFive new isolates of archaeal coccoid thermoacidophiles were obtained from Icelandic solfataric fields. They are strict chemolithoautotrophs gaining energy by oxidation of S° and sulfidic ores. The new strains grow between 50 and 75°C and pH 1 and 4.5 and tolerate NaCl concentrations of up to 3.0%. The GC-content of their DNA is 38 mol%.The new isolates resemble members ofSulfolobusin their morphology, their ability to oxidize reduced sulfur compounds and their GC-content. They are different in their strictly chemolithoautotrophic mode of life, their ore-leaching capacity, DNA/DNA hybridization and incomplete serological cross-reaction of RNA polymerase. Therefore, we describe here a new species,Sulfolobus metallicus. Type strain isSulfolobus metallicus(Kra 23; DSM 6482).
