A Gram-positive, aerobic, non-motile actinobacterial strain, designated YIM C01235T, was isolated from a soil sample collected from the Swallow Cave, Yunnan province, south-west China. The isolate grew at 10–30 °C, pH 6.0–9.0 and 0–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed highest similarity to Saccharopolyspora gloriosae YIM 60513T (96.8 %), and lower 16S rRNA gene sequence similarities (95.1–96.7 %) with the other species of the genus Saccharopolyspora. The whole-cell hydrolysates contained meso-diaminopimelic acid (meso-DAP), arabinose and galactose. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylmethylethanolamine, two unknown glycolipids, two unknown phospholipids and one polar lipid. MK-9(H4) was the predominant menaquinone. The major fatty acids were iso-C15:0, iso-C16:0, anteiso-C15:0 and anteiso-C17:0. Mycolic acids were not detected. The genomic DNA G+C content was 69.1 mol%. These chemotaxonomic data, together with its morphological properties, were consistent with the assignment of strain YIM C01235T to the genus Saccharopolyspora. The results of physiological and biochemical tests allowed strain YIM C01235T to be differentiated phenotypically from all the recognized Saccharopolyspora species. On the basis of evidence from this polyphasic study, the novel species Saccharopolyspora cavernae sp. nov. is proposed. The type strain is YIM C01235T (=DSM 45825T = CCTCC AA 2012022T). 相似文献

A Gram-positive, moderately halophilic, strictly aerobic bacterium, designated YIM 93624T, was isolated from a salt lake in Xinjiang province of China and subjected to a polyphasic taxonomic study. Strain YIM 93624T grew at 15–45 °C (optimum 25–30 °C), 1–17% (w/v) NaCl (optimum 5–10 %, w/v) and pH 4.0–9.0 (optimum pH 7.0). The predominant menaquinone was found to be MK-7. The major fatty acids were anteiso-C15:0 and C16:0. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, a glycolipid and two unidentified phospholipids. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The G+C content of the genomic DNA was 37.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 93624T was a member of the genus Virgibacillus and exhibited the highest similarity of 97.0 % to Virgibacillus koreensis KCTC 3823T. However, the level of DNA–DNA relatedness between strain YIM 93624T and V. koreensis KCTC 3823T was 32.5 %. On the basis of phylogenetic, physiological and chemotaxonomic analysis data, the isolate is concluded to represent a novel species of the genus Virgibacillus, for which the name Virgibacillus albus sp. nov., is proposed, with type strain of YIM 93624T (=DSM 23711T = JCM 17364T). 相似文献

A Streptomyces-like actinomycete strain, designated as YIM 78087T, was isolated from a sediment sample collected from Hehua hot spring in Tengchong, Yunnan province, south-west China. The taxonomic position of strain YIM 78087T was investigated by a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain YIM 78087T belongs to the genus Streptomyces and is closely related to Streptomyces fimbriatus DSM 40942T, Streptomyces marinus DSM 41968T and Streptomyces qinglanensis DSM 42035T (97.18, 97.05 and 97.1 % similarity, respectively). Combined with the low values of DNA–DNA hybridization between strain YIM 78087T and its closest neighbours, these analyses indicated that this new isolate represents a different genomic species in the genus Streptomyces. The predominant menaquinones of strain YIM 78087T were identified as MK-9 (H4) and MK-9 (H6). The major fatty acids were identified as anteiso-C15:0 (28.4 %), anteiso-C17:0 (23.0 %) and iso-C16:0 (15.1 %). The whole-cell hydrolysates found to contain glucose, mannose and ribose. The DNA G+C content was determined to be 73.0 mol%. Based on the comparative analysis of phenotypic and genotypic characteristics, it is proposed that strain YIM 78087T represents a novel species of the genus Streptomyces, for which the name Streptomyces calidiresistens sp. nov., is proposed. The type strain is YIM 78087T (=BCRC 16955T=DSM 42108T=JCM 19629T). 相似文献

A Gram-negative and aerobic bacterium, designated YIM 77875T, was isolated from a geothermal soil sample collected at Rehai National Park, Tengchong, Yunnan Province, south-west China. Bacterial growth occurred from 37 to 65 °C (optimum 50 °C), pH 6.0–8.0 (optimum pH 7.0) and 0–1 % NaCl (w/v). Cells were rod-shaped and colonies were convex, circular, smooth, yellow and non-transparent. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain YIM 77875T belongs to the genus Lysobacter. The 16S rRNA gene sequence similarity values between strain YIM 77875T and other species of the genus Lysobacter were all below 94.7 %. The polar lipids of strain YIM 77875T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and five unknown phospholipids. The predominant respiratory quinone was Q-8 and the G+C content was 68.8 mol%. Major fatty acids were iso-C16:0, iso-C15:0 and iso-C11:0. On the basis of the morphological and chemotaxonomic characteristics, as well as genotypic data, strain YIM 77875T represents a novel species, Lysobacter thermophilus sp. nov., in the genus Lysobacter. The type strain is YIM 77875T (CCTCC AB 2012064T = KCTC 32020T). 相似文献

Three halophilic mycelium-forming actinobacteria, strains H195T, H150 and H151, were isolated from a Saharan soil sample collected from Béni-isguen in the Mzab region (Ghardaïa, South of Algeria) and subjected to a polyphasic taxonomic characterisation. These strains were observed to show an aerial mycelium differentiated into coccoid spore chains and fragmented substrate mycelium. Comparative analysis of the 16S rRNA gene sequences revealed that the highest sequence similarities were to Saccharopolyspora qijiaojingensis YIM 91168T (92.02 % to H195T). Phylogenetic analyses showed that the strains H195T, H150 and H151 represent a distinct phylogenetic lineage. The cell-wall hydrolysate was found to contain meso-diaminopimelic acid, and the diagnostic whole-cell sugars were identified as arabinose and galactose. The major cellular fatty acids were identified as iso-C15:0, iso-C16:0, iso-C17:0 and anteiso-C17:0. The diagnostic phospholipid detected was phosphatidylcholine and MK-9 (H4) was found to be the predominant menaquinone. The genomic DNA G+C content of strain H195T was 68.2 mol%. On the basis of its phenotypic features and phylogenetic position, we propose that strain H195T represents a novel genus and species, Mzabimyces algeriensis gen. nov., sp. nov., within a new family, Mzabimycetaceae fam. nov. The type strain of M. algeriensis is strain H195T (=DSM 46680T = MTCC 12101T). 相似文献

Two actinomycete strains, designated YIM M11168T and YIM M11177, were isolated from marine sediment samples from Little Andaman, Indian Ocean, and their taxonomic position was determined by a polyphasic approach. The two Gram-positive, aerobic strains were observed to produce branched substrate mycelium and aerial hyphae but did not fragment, and no diffusible pigment was produced on the media tested. At maturity, spores were formed singly or in pairs on aerial hyphae and substrate mycelium, and occasionally the single ones were borne on long sporophores. The optimum growth was determined to occur at 28 °C, 0–4 % (w/v) NaCl and pH 7.0–8.0. Whole-cell hydrolysates of both strains contained meso-diaminopimelic acid and the diagnostic sugars were determined to be galactose, glucose and arabinose. Their predominant menaquinone was found to be MK-9(H4). The polar lipids detected in the two strains were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, phosphatidylmethylethanolamine, phosphatidylethanolamine and two unknown phosphoglycolipids. The major fatty acids (>10 %) identified were iso-C16:0, iso-C16:1 H, iso-C16:0, C17:1 ω6c for strain YIM M11168T, iso-C16:0 and Summed Feature 3 for strain YIM M11177. The G + C contents of the genomic DNAs of both strains were determined to be 71.4 %. DNA–DNA hybridization relatedness values (78.4 ± 3.7 %) of these two isolates supported the conclusion that they belong to the same species. Based on phylogenetic analysis, phenotypic and genotypic data, it is concluded that the two isolates belong to a novel species of the genus Saccharomonospora of the family Pseudonocardiaceae. The name Saccharomonospora oceani sp. nov. (Type strain YIM M11168T = DSM 45700T = JCM 18128T) is proposed for the novel species. 相似文献

A Gram-stain negative aerobic bacterium, designated YIM 77924T, was isolated from a geothermally heated soil sample collected at Rehai National Park, Tengchong, Yunnan province, south-west China. Growth was found to occur from 55 to 75 °C (optimum 65 °C), pH 6.0–8.0 (optimum pH 7.0) and 0–1 % NaCl (w/v). Cells were observed to be rod-shaped and the colonies convex, circular, smooth, yellow and non-transparent. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain YIM 77924T belongs to the genus Thermus. The 16S rRNA gene sequence similarity values between strain YIM 77924T and other species of the genus Thermus were all below 97 %. The polar lipids of strain YIM 77924T were determined to be aminophospholipid, phospholipid and glycolipid. The predominant respiratory quinone was determined to be MK-8 and the G+C content was 66.64 mol%. The major fatty acids identified were iso-C16:0, iso-C15:0, iso-C17:0 and C16:0. On the basis of the morphological and chemotaxonomic characteristics as well as genotypic data, strain YIM 77924T is proposed to represent a novel species, Thermus tengchongensis sp. nov., in the genus Thermus. The type strain is YIM 77924T (=KCTC 32025T = CCTCC AB2012063T). 相似文献

A thermotolerant Gram-staining negative and aerobic bacterium, designated strain YIM 77520T, was isolated from a geothermally heated soil sample collected at Rehai National Park, Tengchong, Yunnan Province, South-West China. Cells of the strain were found to be rod-shaped and colonies were light beige and circular. The strain was found to grow in the presence of 0–2 % (w/v) total salts (optimum, 0 %), at pH 6.0–8.0 (optimum, pH 7.0) and 25–55 °C (optimum, 45 °C). The only quinone detected was Q-8 and the genomic DNA G+C content was determined to be 66.9 mol%. The major fatty acids (>10 %) were identified as iso-C16:0 and iso-C15:0. The phospholipids were found to consist of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, five unknown phospholipids and three aminophospholipids. Based on the 16S rRNA gene sequence analysis, strain YIM 77520T was found to form a cluster with Lysobacter thermophilus YIM 77875T and showed the highest 16S rRNA gene sequence similarity to L. thermophilus YIM 77875T (96.0 %). These two strains formed a distinct lineage of the family ‘Xanthomonadaceae’. On the basis of the morphological and chemotaxonomic characteristics, as well as genotypic data, a new genus, Vulcaniibacterium gen. nov. is proposed with Vulcaniibacterium tengchongense sp. nov. as the type species. The type strain of V. tengchongense sp. nov. is strain YIM 77520T (=DSM 25623T = CCTCC AB 2011152T). Furthermore we propose that L. thermophilus Wei et al. 2012 is reclassified in the new genus as Vulcaniibacterium thermophilum comb. nov. (type strain YIM 77875T = CCTCC AB 2012064T = KCTC 32020T) based on polyphasic data. 相似文献

A Gram-positive, coccoid, non-endospore-forming actinobacterium, designated YIM C01117T, was isolated from a soil sample collected from Alu ancient cave, Yunnan province, south-west China. Based on the 16S rRNA gene sequence analysis, strain YIM C01117T was shown to belong to the genus Microlunatus, with highest sequence similarity of 97.4 % to Microlunatus soli DSM 21800T. The whole genomic DNA relatedness as shown by the DNA–DNA hybridization study between YIM C01117T and M. soli DSM 21800T had a low value (47 ± 2 %). Strain YIM C01117T was determined to contain LL-diaminopimelic acid with Gly, Glu and Ala amino acids (A3γ′ type) in the cell wall. Whole-cell hydrolysates were found to contain glucose, galactose, mannose and ribose. The major polar lipids were determined to be phosphatidylglycerol and diphosphatidylglycerol. The predominant menaquinone system present is MK-9(H4), while the major fatty acids were identified to be anteiso-C15:0 (24.1 %), iso-C16:0 (22.3 %) and iso-C15:0 (11.4 %). The G+C content of the genomic DNA was determined to be 65.9 mol%. The chemotaxonomic and genotypic data support the affiliation of the strain YIM C01117T to the genus Microlunatus. The results of physiological and biochemical tests allow strain YIM C01117T to be differentiated phenotypically from recognized Microlunatus species. Strain YIM C01117T is therefore considered to represent a novel species of the genus Microlunatus, for which the name Microlunatus cavernae sp. nov. is proposed. The type strain is YIM C01117T (= DSM 26248T = JCM 18536T). 相似文献

A Gram-positive, moderately halotolerant, rod-shaped bacterium, designated YIM 94025T, was isolated from a soil sample from a salt lake in Xinjiang province, north-west China. Strain YIM 94025T was observed to grow at 25–45 °C (optimum 37 °C), 0–22 % NaCl (optimum 2–10 %) and pH 6.0–9.0 (optimum pH 8.0). Phylogenetic analyses based on 16S rRNA gene sequences revealed that the organism belongs to the genus Tenuibacillus and exhibited sequence similarity of 98.0 % to the closest type strain, Tenuibacillus multivorans AS 1.3442T. The predominant menaquinone was found to be MK-7; the cell-wall peptidoglycan diamino acid was meso-diaminopimelic acid; the polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, an unidentified phospholipid and an unknown lipid; and the major fatty acids were found to contain iso-C15:0, anteiso-C15:0 and iso-C16:0. The chemotaxonomic characteristics of strain YIM 94025T are consistent with those of the genus Tenuibacillus. The level of DNA–DNA relatedness value between YIM 94025T and T. multivorans AS 1.3442T was 36.6 ± 4.5 %. The G+C content of the strain YIM 94025T was determined to be 38.5 %. Based on the comparative analysis of physiological, biochemical and chemotaxonomic data, as well as DNA–DNA hybridization results, the isolate is considered to represent a novel species of the genus Tenuibacillus, for which the name Tenuibacillus halotolerans sp. nov., is proposed, with the type strain of YIM 94025T (=CCTCC AB 2012860T = KCTC 33046T). 相似文献

An alkalitolerant, thermotolerant, strictly aerobic and Gram-staining negative bacterial strain, designated YIM 78140T, was isolated from a water sample in Hehua hot spring, Tengchong, Yunnan province, south-west China. The colonies were light brown, convex and circular. Phylogenetic analysis of the 16S rRNA gene sequence of strain YIM 78140T indicated that it was clustered with members of β-Proteobacteria (with the similarity from 96.9 to 93.6 %). Good growth occurred at 40–50 °C, pH 8.0–9.0 and in the presence of 0–3 % (w/v) NaCl. The predominant ubiquinones were Q-8 and Q-9. The major fatty acids were C16:0, C17:0 cyclo, C18:1 ω7c and summed feature 3. The G+C content of genomic DNA was 70.8 mol%. The results of physiological and biochemical characteristics, phylogenetic analysis allowed the phenotypic and genotypic differentiation of strain YIM 78140T from its closest phylogenetic neighbours. Therefore, the strain YIM 78140T represents a novel genus of the family Comamonadaceae, for which the name Zhizhongheella caldifontis gen. nov., sp. nov. is proposed. The type strain is YIM 78140T (= BCRC 80649T = KCTC 32557T). 相似文献

A novel aerobic, Gram-positive, non-motile halotolerant actinobacterium, designated strain YIM 96448T, was isolated from a saline soil sample collected from the south bank of Aiding Lake in Xinjiang Province, northwest China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YIM 96448T is closely related to Phytoactinopolyspora endophytica EGI 60009T (98.0%) and Phytoactinopolyspora alkaliphila EGI 80629T (97.0%). Optimum growth of the strain was observed at 28-37 °C, pH 7–9 and in the presence of 5–8% NaCl (w/v). The respiratory quinone of strain YIM 96448T was determined to be MK-9(H4). The major fatty acids (>10%) were identified as anteiso-C15:0, iso-C16:0, anteiso-C17:0 and summed feature 4 (iso-C17:1 I and/or anteiso-C17:1B). The polar lipid profile was found to consist of diphosphatidylglycerol, an unidentified aminophospholipid, phosphatidylglycerol, two phosphatidylinositol mannosides, three unidentified phosphoglycolipids and four unidentified phospholipids. The DNA G+C content was determined to be 68.7 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analysis, strain YIM 96448T should be classified as a novel species in the genus Phytoactinopolyspora, for which the name Phytoactinopolyspora halotolerans sp. nov. is proposed. The type strain is YIM 96448T (=CCTCC AB 2017055T = KCTC 39924T). 相似文献

A Gram-positive, moderately halophilic, facultatively alkaliphilic, catalase- and oxidase-positive, obligately aerobic, filamentous
actinomycete strain, designated YIM 90022T, was isolated from saline soil collected from the Qaidam Basin, north-west China. Phylogenetic analysis based on 16S rRNA
gene sequences indicated that the new isolate was a member of the genus Nocardiopsis and the sequence similarities between the isolate and the type strains of members of the genus Nocardiopsis were in the range of 95.1–98.7%. Phenotypic and chemotaxonomic properties of this organism also indicated that strain YIM
90022T was a member of the genus Nocardiopsis. The strain grew well on most of the media tested, producing yellow-white to deep brown substrate mycelium and white aerial
mycelium. Light gray to deep brown diffusible pigments were produced. The substrate mycelium was well developed and fragmented
with age; the aerial mycelium produced long, straight to flexuous spore chains with non-motile, smooth-surfaced, rod-shaped
spores on them. The strain grew in the presence of 1–15% (w/v) total salts (optimum, 3–5%) and at pH 6.0–10.5 (optimum, pH
8.5) and 10–45°C (optimum, 30°C). Whole-cell hydrolysates of strain YIM 90022T contained meso-diaminopimelic acid and no diagnostic sugars. The predominant menaquinones were MK-10(H4), MK-9(H8), MK-10(H6) and MK-10(H8). Polar lipids comprised diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol and phosphatidylmethylethanolamine.
The major cellular fatty acids were iso-C16:0, anteiso-C17:0, 10-methyl-C18:0 and 10-methyl-C17:0. The DNA G + C content of strain YIM 90022T was 71.5 mol%. The combination of phylogenetic analysis, DNA–DNA relatedness data, phenotypic characteristics and chemotaxonomic
data supported the suggestion that strain YIM 90022T represents a new species of the genus Nocardiopsis, for which the name Nocardiopsis terrae sp. nov. is proposed. The type strain is YIM 90022T (=CCTCC AA 208011T =KCTC 19431T). 相似文献

A novel endophytic actinomycete, designated strain NEAU-J3T, was isolated from soybean root (Glycine max (L.) Merr) and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain NEAU-J3T fell within the family Micromonosporaceae. The strain was observed to form an extensively branched substrate mycelium, which carried non-motile oval spores with a smooth surface. The cell walls of strain NEAU-J3T were determined to contain meso-diaminopimelic acid and galactose, ribose and glucose were detected as whole-cell sugars. The major menaquinones were determined to be MK-9(H4) and MK-9(H6). The phospholipids detected were phosphatidylcholine and phosphatidylethanolamine. The major cellular fatty acids were determined to be C16:0, C18:1 ω9c, C18:0, C17:0, C17:1 ω7c, anteiso-C17:0, C16:1 ω7c and C15:0. The DNA G + C content was 62.5 mol%. On the basis of the morphological and chemotaxonomic characteristics, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain NEAU-J3T is considered to represent a novel species of a new genus within the family Micromonosporaceae, for which the name Wangella harbinensis gen. nov., sp. nov. is proposed. The type strain of Wangella harbinensis is strain NEAU-J3T (=CGMCC 4.7039T = DSM 45747T). 相似文献

A halophilic actinomycete strain, designated H27T, was isolated from a soil sample collected from a hypersaline habitat in Djelfa Province (North-Central Algeria), and then investigated using a polyphasic taxonomic approach. The strain was observed to produce poor aerial mycelium, which formed short chains of oval to cylindrical-shaped spores at maturity, and non fragmented substrate mycelium. The optimum NaCl concentration for growth was found to be 10–15 % (w/v) and the optimum growth temperature and pH were found to be 28–37 °C and 6–7, respectively. The diagnostic diamino acid in the cell-wall peptidoglycan was identified as meso-diaminopimelic acid. The predominant menaquinones of strain H27T were identified as MK-11 (H4) and MK-10 (H6). The major fatty acids were found to be iso-C16:0, anteiso-C17:0, 10 methyl C17:0 and 10 methyl C16:0. The diagnostic phospholipids detected were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and phosphatidylinositol. The chemotaxonomic properties of strain H27T are consistent with those shared by members of the genus Streptomonospora. 16S rRNA gene sequence analysis indicated that strain H27T is most closely related to Streptomonospora alba DSM 44588T (98.8 %) and Streptomonospora flavalba DSM 45155T (98.7 %) whereas the DNA–DNA relatedness values between strain H27T and the two type strains were 17.1 and 57.9 %, respectively. Based on the combined genotypic and phenotypic evidence, it is proposed that strain H27T should be classified as representative of a novel species, for which the name Streptomonospora algeriensis sp. nov. is proposed. The type strain is H27T (=DSM 45604T =CCUG 63369T =MTCC 11563T). 相似文献

A Gram-stain positive, facultative anaerobic endospore-forming bacterium, designated strain YIM h-19T, was isolated from a tobacco sample. Cells were observed to be motile rods by means of peritrichous flagella and colonies were observed to be convex, yellow, circular and showed catalase-positive and oxidase-negative reactions. Strain YIM h-19T was able to grow at 4–45 °C, pH 6.0–8.0 and 0–3 % NaCl (w/v). The predominant respiratory quinone was identified as MK-7. Major fatty acids were identified as anteiso-C15:0, anteiso-C17:0 and C16:0. The polar lipids were found to be phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and two unidentified polar lipids. The genomic DNA G+C content was determined to be 54 mol%. 16S rRNA gene sequence analysis showed the strain YIM h-19T was most closely related to Paenibacillus hordei RH-N24T and Paenibacillus hunanensis FeL05T with similarities of 98.30 and 94.64 % respectively. However, DNA–DNA hybridization data indicated that the isolate represented a novel genomic species with the genus Paenibacillus. All data from genotypic and phenotypic analyses support the conclusion that strain YIM h-19T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus nicotianae sp. nov. is proposed. The type strain is YIM h-19T (=CGMCC1.12819T = NRRL B-59112T). 相似文献

A novel Gram-positive, rod-shaped, motile, spore-forming, nitrogen-fixing bacterium, designated strain 7188T, was isolated from jujube rhizosphere soil in Beijing, China. The strain grew at 4–40 °C and pH 6–12, with an optimum of 30 °C and pH 7.0, respectively. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain 7188T is a member of the genus Paenibacillus. Levels of 16S rRNA gene sequence similarities between strain 7188T and the type strains of all recognized members of the genus Paenibacillus were below 96 %. The major cellular fatty acids were anteiso-C15:0, anteiso-C17:0 and C16:0. The predominant menaquinone was MK-7. The DNA G+C content of strain 7188T was 60.3 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and unknown aminophospholipids. The diamino acid in the cell wall peptidoglycan is meso-diaminopimelic acid. On the basis of these results, strain 7188T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus beijingensis sp. nov. is proposed. The type strain is 7188T (=ACCC 03082T = DSM 24997T). 相似文献

Bacillus alkalicola sp. nov., An Alkaliphilic,Gram-Positive Bacterium Isolated from Zhabuye Lake in Tibet,China 总被引:1,自引:0,他引:1
A Gram-positive, alkaliphilic bacterium, designated strain Zby6T, was isolated from Zhabuye Lake in Tibet, China. The strain was able to grow at pH 8.0–11.0 (optimum at pH 10.0), in 0–8 % (w/v) NaCl (optimum at 3 %, w/v) and at 10–45 °C (optimum at 37 °C). Cells of the isolate were facultatively anaerobic and spore-forming rods with polar flagellum. The predominant isoprenoid quinone was MK-7, and its cell wall peptidoglycan contained meso-diaminopimelic acid. The major cellular fatty acids were iso-C15:0, C16:0 and anteiso-C15:0. The major polar lipids consisted of phosphatidylglycerol, diphosphatidylglycerol, and phosphatidylethanolamine. The genomic DNA G+C content of the isolate was 38.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Zby6T was a member of the genus Bacillus and most closely related to Bacillus cellulosilyticus DSM 2522T (97.7 % similarity). The DNA–DNA relatedness value between strain Zby6T and B. cellulosilyticus DSM 2522T was 59.2 ± 1.8 %. Comparative analysis of genotypic and phenotypic features indicated that strain Zby6T represents a novel species of the genus Bacillus, for which the name Bacillus alkalicola sp. nov. is proposed; the type strain is Zby6T (=CGMCC 1.10368T = JCM 17098T = NBRC 107743T). 相似文献

An orange-coloured, non-spore-forming, motile and coccus-shaped actinobacterium, designated YIM 75677T, was isolated from a soil sample collected from a dry-hot river valley in Dongchuan county, Yunnan Province, south-west China and its taxonomic position was investigated. Growth of strain YIM 75677T occurred at 12–55 °C, pH 6.0–9.0 and NaCl tolerance up to 2 % (w/v). Cells adhered to agar media and were agglutinated tightly together. The peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid. The whole-cell hydrolysates mainly contained glucose, galactose, mannose and ribose. The predominant menaquinone was MK-9 (H2) and the major fatty acids were anteiso-C15:0 and iso-C15:0. Mycolic acids were not present. The DNA G+C content of strain YIM 75677T was 74.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequence comparisons clearly revealed that strain YIM 75677T represents a novel member of the genus Kineococcus and is closely related to Kineococcus xinjiangensis S2-20T (level of similarity, 98.6 %). Meanwhile, the result of DNA–DNA hybridization between strain YIM 75677T and K. xinjiangensis S2-20T demonstrated that this isolate represented a different genomic species in the genus Kineococcus. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain YIM 75677T represents a novel species of the genus Kineococcus, for which the name Kineococcus glutineturens sp. nov. is proposed. The type strain is YIM 75677T (=CCTCC AA 209075T = JCM 18126T). 相似文献
