A marine bacterium designated strain IMCC4074T was isolated from surface seawater collected off Incheon Port, the Yellow Sea, and subjected to a polyphasic taxonomy. The strain was Gram-negative, chemoheterotrophic, slightly halophilic, strictly aerobic, and motile rods. Based on 16S rRNA gene sequence comparisons, the strain was most closely related to Marinobacterium litorale KCTC 12756T (93.9%) and shared low 16S rRNA gene sequence similarities with members of the genus Marinobacterium (91.8–93.9%) and the genus Neptunomonas (93.4%) in the order Oceanospirillales. Phylogenetic analyses showed that this marine isolate formed an independent phyletic line within the genus Marinobacterium clade. The DNA G+C composition of the strain was 56.0 mol% and the predominant constituents of the cellular fatty acids were C16:0 (28.0%), C16:1 ω7c and/or iso-C15:0 2-OH (19.3%), C18:1 ω7c (17.8%), and C17:1 cyclo (12.5%), which differentiated the strain from other Marinobacterium species. Based on the taxonomic data collected in this study, only a distant relationship could be found between strain IMCC4074T and other members of the genus Marinobacterium, thus the strain represents a novel species of the genus Marinobacterium, for which the name Marinobacterium marisflavi sp. nov. is proposed. The type strain of Marinobacterium marisflavi is IMCC4074T (= KCTC 12757T = LMG 23873T). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain IMCC4074T is EF468717.

A Gram-positive, rod-shaped, motile and spore-forming bacterium, designated ZLD-8T, was isolated from a desert soil sample collected from Xinjiang Province in north-west China, and subjected to a polyphasic taxonomic analysis. This isolate grew optimally at 30°C and pH 7.0. It grew with 0–4% NaCl (optimum, 0–1%). Comparative 16S rRNA gene sequence analysis showed that strain ZLD-8T was closely related to members of the genus Bacillus, exhibiting the highest 16S rRNA gene sequence similarity to Bacillus kribbensis DSM 17871T (98.0%). The levels of 16S rRNA gene sequence similarity with respect to other Bacillus species with validly published names were less than 96.3%. The DNA G + C content of strain ZLD-8T was 40.1 mol%. The strain contained MK-7 as the predominant menaquinone. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids (>5% of total fatty acids) were anteiso-C15:0 (39.56%), iso-C14:0 (25.69%), C16:1 ω7c alcohol (10.13%) and iso-C15:0 (5.27%). These chemotaxonomic results supported the affiliation of strain ZLD-8T to the genus Bacillus. However, low DNA–DNA relatedness values and distinguishing phenotypic characteristics allowed genotypic and phenotypic differentiation of strain ZLD-8T from recognized Bacillus species. On the basis of the polyphasic evidence presented, strain ZLD-8T is considered to represent a novel species of the genus Bacillus, for which the name Bacillus deserti sp. nov. is proposed. The type strain is ZLD-8T (=CCTCC AB 207173T = KCTC 13246T).  相似文献

A gram-negative, motile, straight to curved rod shaped, pink pigmented bacterium was isolated from a soil sample collected from the rhizosphere of an Indian medicinal plant, Nerium indicum (Chuvanna arali) and subjected to a detailed polyphasic taxonomic study. The strain, designated as IMTB-1969T, matched with most of the phenotypic and chemotaxonomic properties of the genus Pontibacter and represents a novel species. The major fatty acids of the strain were monounsaturated iso/anteiso branched C17 fatty acids (45.1%) and iso-C15:0 (16.5%). MK-7 was the predominant isoprenoid quinone. According to 16S rRNA gene sequence analysis, strain IMTB-1969T was indicated to belonged to the phylum Bacteroidetes and further phylogenetic analysis revealed that the strain IMTB-1969T belongs to the family Cytophagaceae and genus Pontibacter. The highest 16S rRNA gene sequence similarity was with Pontibacter korlensis CCTCC AB 206081T (97.2%) and lower sequence similarity was observed with other species in the genus Pontibacter (95.9–94.0%). DNA–DNA relatedness study of the strain IMTB-1969T confirmed that it represents a novel species. The G+C content of the genomic DNA was 52.2 (±0.5) mol%. The results of physiological and biochemical tests allowed the genotypic and phenotypic distinction of strain IMTB-1969T from its closest phylogenetic relatives. The strain IMTB-1969T should be classified as novel species of the genus Pontibacter, for which the name Pontibacter rhizosphera sp. nov. is proposed. The type strain is IMTB-1969T (=MTCC 10673T = DSM 24399T).  相似文献

A strain named A18 was recovered from a compost of button mushrooms. It was characterized using a polyphasic approach. On the basis of 16S rRNA gene sequence comparison, it belonged to the genus Nocardiopsis and was most closely related to the type strains of Nocardiopsis flavescens (sequence similarity 98.0%), Nocardiopsis prasina (97.5%), Nocardiopsis metallicus (97.4%), Nocardiopsis alba (97.3%). The combination of phylogenetic analysis, DNA–DNA hybridization, phenotypic characteristics and chemotaxonomic data supported the proposal that strain A18 represents a new species of the genus Nocardiopsis, for which the name Nocardiopsis yanglingensis sp. nov. was proposed (type strain A18T = KCTC 19723T = CCTCC 209063T).  相似文献

A Gram-negative, short ovoid- to coccus-shaped, aerobic, motile, non-spore-forming bacterium (designated strain JLT1679T) was isolated from West Pacific. Cells have subpolar flagella, dividing by binary fission. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain belongs to branch of the evolutionary radiation occupied by the genus Paracoccus, family Rhodobacteraceae, order Rhodobacterales, class Alphaproteobacteria. The closest neighbours were Paracoccus stylophorae KTW-16T (97.1% similarity), Paracoccus caeni strain MJ17T (96.5% similarity), Paracoccus homiensis DD-R11T (96.0% similarity) and Paracoccus alcaliphilus JCM 7364T (95.8% similarity). The predominant cellular fatty acids of strain JLT1679T were summed feature 8 (18:1ω6c) (38.8%), C18:0 (27.7%), C16:0 (22.5%), and significant amounts of C18:1 ω9c (5.1%), C14:0 (3.8%) and C18:1 ω7c 11-methyl (2.1%), were present. The predominant respiratory ubiquinone of strain JLT1679T was Q-10 and the DNA G + C content of strain JLT1679T was 59.5 mol%. The polar lipid profile consisted of a mixture of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. The isolate was distinguishable from members of the genus Paracoccus on the basis of phenotypic and biochemical characteristics. It is evident from the genotypic, chemotaxonomic and phenotypic data that strain JLT1679T represents a novel species of the genus Paracoccus, for which the name Paracoccus oceanense sp. nov. is proposed. The type strain is JLT1679T (= JCM 17768T = CGMCC 1.10831T).  相似文献

The alphaproteobacterial strain JLT2003T 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 C18:1ω7c, cyclo C19:0ω8c, and C16:0. 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 GRP21T 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 JLT2003T 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 JLT2003T (=JCM 17765T = CGMCC 1.10827T).  相似文献

A novel actinomycete, designated KLBMP 1221T, was isolated from the surface-sterilized seeds of an oil-seed plant Jatropha curcas L. collected from Sichuan Province, south-west China and was characterized taxonomically by using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequence showed that this strain formed a distinct phyletic line within the radiation of the genus Amycolatopsis. The 16S rRNA gene sequence similarity indicated that strain KLBMP 1221T was most closely related to Amycolatopsis eurytherma NT202T (98.9%), Amycolatopsis tucumanensis ABOT (98.8%), Amycolatopsis thermoflava N1165T (98.6%) and Amycolatopsis methanolica IMSNU 20055T (98.5%). Strain KLBMP 1221T had morphological and chemotaxonomic properties that were consistent with its classification in the genus Amycolatopsis. However, DNA–DNA relatedness data and phenotypic differences clearly distinguished the isolate from its closest relatives. Based on the combined genotypic and phenotypic evidence, it is proposed that strain KLBMP 1221T be classified as representative of a novel species for which the name Amycolatopsis endophytica sp. nov. is proposed. The type strain is KLBMP 1221T (= KCTC 19776T = CCTCC AA 2010003T).  相似文献

A novel Gram-negative, catalase- and oxidase-positive, strictly aerobic, non spore-forming, rod-shaped bacterium, designated strain JSM 083058T, was isolated from non-saline forest soil in Hunan Province, China. Growth occurred with 0–8% (w/v) NaCl (optimum, 0.5–3%) at pH 6.0–10.0 (optimum, pH 7.0) and at 5–35°C (optimum, 25–30°C). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 083058T fell within the cluster comprising species of the genus Sphingomonas, clustering with Sphingomonas aestuarii K4T, with which it shared highest 16S rRNA gene sequence similarity (99.2%). The chemotaxonomic properties of strain JSM 083058T were consistent with those of the genus Sphingomonas. The predominant respiratory quinone was ubiquinone Q-10, and the major cellular fatty acids were summed feature 8 (C18:1ω7c/C18:1ω6c), C16:0, summed feature 3 (C16:1ω7c/C16:1ω6c) and C17:1ω6c. The polar lipids consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid. The genomic DNA G+C content of strain JSM 083058T was 65.5 mol%. The combination of phylogenetic analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain JSM 083058T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas hunanensis sp. nov. is proposed. The type strain is JSM 083058T (=CCTCC AA 209011T = DSM 22213T).  相似文献

An agarolytic bacterium, designated as strain M5cT, was isolated from sea sand in Jeju Island, Korea. This isolate was Gram-negative, positive for catalase and oxidase, rod and motile by means of monotrichous flagella. Strain M5cT has translucent or dark ivory colonies, forms a dent on an agar plate under colonies, and grows in the presence of 1–12% (w/v) NaCl and at 10–37°C. This isolate hydrolyzes agar, alginic acid, carboxymethyl (CM)-cellulose and starch. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain M5cT can be considered as a species within the genus Gilvimarinus, being most closely related to Gilvimarinus chinensis QM42T, with a 16S rRNA gene sequence similarity of 95.6%. The major cellular fatty acids were C16:1ω7c and/or iso-C15:0 2OH (33.5%), C16:0 (26.5%) and C18:1ω7c (14.1%). The DNA G+C content was 53.8 mol%. Based on these polyphasic data, strain M5cT should be classified as a novel species, for which the name Gilvimarinus agarilyticus sp. nov. is proposed. The type strain for the novel species is M5cT (= KCTC 23325T = NCAIM B 02425T).  相似文献

The taxonomic study of two Gram-negative, aerobic, non-pigmented bacteria KMM 9010T and KMM 9023T isolated from a sandy sediment sample collected from the Sea of Japan seashore was performed. On the basis of the nearly complete 16S rRNA gene sequences, strains KMM 9010T and KMM 9023T clustered with the Roseobacter lineage (class Alphaproteobacteria) forming a distinct phylogenetic line adjacent to the genus Donghicola. Novel strains shared the highest sequence similarity of 96.4% to each other and lower than 96.1% similarities to other validly named genera of the class Alphaproteobacteria. In both strains, ubiquinone Q-10 was found to be the major respiratory quinone; phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidic acid, and an unknown aminolipid were the major polar lipids and C18:1ω7c and 11-methyl C18:1ω7c were predominant fatty acids. The DNA G+C content was 60.5 mol% (KMM 9010T) and 65.4 mol% (KMM 9023T). Based on phenotypic properties and phylogenetic evidence, strains KMM 9010T and KMM 9023T should be classified as two novel species in a new genus, Poseidonocella gen. nov., with Poseidonocella pacifica sp. nov., the type species with the type strain KMM 9010T (= NRIC 0794T = JCM 17310T), and Poseidonocella sedimentorum sp. nov. as the second species with the type strain KMM 9023T (= NRIC 0796T = JCM 17311T).  相似文献

Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative, aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth, shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus Flavobacterium. The strains shared 98.6–99.4% sequence similarity with each other and showed less than 97% similarity with members of the genus Flavobacterium with validly published names. The DNA-DNA hybridization results confirmed the separate genomic status of strains ARSA-42T, ARSA-103T, and ARSA-108T. The isolates contained menaqui-none-6 as the predominant menaquinone and iso-C15:0, iso-C15:0 3-OH, iso-Ci15:1 G, and iso-C16:0 3-OH as the major fatty acids. The genomic DNA G+C content of the isolates were 31.4–33.2 mol%. According to the phenotypic and genotypic data, these organisms are classified as representative of three novel species in the genus Flavobacterium, and the name Flavobacterium koreense sp. nov. (strain ARSA-42T =KCTC 23182T =JCM 17066T =KACC 14969T), Flavobacterium chungnamense sp. nov. (strain ARSA-103T =KCTC 23183T =JCM 17068T =KACC 14971T), and Flavobacterium cheonanense sp. nov. (strain ARSA-108T =KCTC 23184T =JCM 17069T =KACC 14972) are proposed.  相似文献

A novel actinomycete strain, designated TRM 40133T, was isolated from a hypersaline habitat of Tarim basin in Xinjiang Province, north-west China. Its taxonomic status was determined using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a well-seperated sub-branch within the radiation of the genus Saccharopolyspora. The highest levels of 16S rRNA gene sequence similarity was found between the strain TRM 40133T and Saccharopolyspora qijiaojingensis YIM 91168T (96.5%). The chemotaxonomic characteristics of the isolate are typical for the genus Saccharopolyspora. It contained meso-DAP as the diagnostic diamino acid. Whole cell hydrolysate contained arabinose, xylose, ribose and glucose. The diagnostic phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and two unknown phospholipids. The main menaquinone was MK-9(H6) and MK-9(H4). No mycolic acid was detected. The predominant cellular fatty acids were iso-C16:0 and anteiso-C17:0. The G+C content of the genomic DNA was 68.2 mol%. In addition, the strain TRM 40133T had a phenotypic profile that readily distinguished it from the recognized representatives of the genus Saccharopolyspora. The strain TRM 40133T therefore represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora lacisalsi sp. nov. is proposed. The type strain is TRM 40133T (=KCTC 19987T =CCTCC AA 2010012T).  相似文献

A novel alkaliphilic and moderate halophilic bacterium, designated strain K164T, was isolated from Keke Salt Lake in Qinghai, China. The strain grew with 2.0–20.0% (w/v) NaCl, at 4–50°C and pH 6.5–11.5, with an optimum of 8% (w/v) NaCl, 37°C and pH 10, respectively. The predominant respiratory quinone was menaquinone 6 (MK-6) and the major polar lipid was phosphatidylethanolamine. The major cellular fatty acids were anteiso-C15:0 and iso-C15:0. The genomic DNA G+C content was 50.16 mol. Phylogenetic analysis based on the full-length 16S rRNA gene sequence revealed that strain K164T was a member of the genus Salinicoccus. Strain K164T showed the highest similarity (98.4%) with Salinicoccus alkaliphilus AS 1.2691T and below 97% similarity with other recognized members of the genus in 16S rRNA gene sequence. Level of DNA–DNA relatedness between strain K164T and Salinicoccus alkaliphilus AS 1.2691T was 20.1%. On the basis of its phenotypic characteristics and the level of DNA–DNA hybridization, strain K164T is considered to represent a novel species of the genus Salinicoccus, for which the name Salinicoccus kekensis sp. nov. is proposed. The type strain is K164T (=CGMCC 1.10337T = DSM 23173T).  相似文献

A Gram-negative, non-motile, catalase- and oxidase- positive, strictly aerobic, and short rod-shaped bacterium that was designated strain KOPRI 25157T was isolated from coastal seawater sample in Antarctica. The temperature and pH ranges for growth on R2A agar were 10–20°C, and 5.0–10.0, respectively. Phylogenetic analyses of the 16S rRNA gene sequence of strain KOPRI 25157T showed it to belong to the family Oxalobacteraceae of the class Betaproteobacteria, and it formed a distinct clade from other recognized members of the family. DNA G + C content was 65.9 mol%. Major ubiquinone was Q-8. Predominant cellular fatty acids were C16:1 ω7c/15 iso 2OH (56.4%) and C16:1 (30.5%). Major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, and unknown lipid. On the basis of these data, it is proposed that strain KOPRI 25157T is the representative of a novel genus, for which the name Actimicrobium gen. nov. is proposed in the family Oxalobacteraceae. The type strain for Actimicrobium antarcticum sp. nov. is KOPRI 25157T (=JCM 16673T=KCTC 23040T).  相似文献

A Gram-negative, non-motile, rod shaped, and orange-pigmented chemoheterotrophic bacterium, strain MS-31T was isolated from the marine sponge Hymeniacidon flavia, collected from near Jeju Island, Korea. The Strain MS-31T was subjected to a polyphasic taxonomic study. The phylogenetic analysis based on the 16S rRNA gene sequences revealed that the novel isolate could be affiliated within the genus Sphingomonas. The strain MS-31T showed 95.6% of 16S rRNA gene sequence similarity with the most closely related species Sphingomonas koreensis JSS26T. The DNA G+C content of the strain MS-31T was 69.4 mol%. The major isoprenoid quinone was ubiqunone 10 and predominant cellular fatty acids were summed feature 7 (comprising C18:1 ω7c, C18:1 Ω9t and/or C18:1 ωl2t, 39.7%), C16:0 (16.3%), C14:0 2OH (15.9%) and summed feature 3 (comprising C16:1 ω7c and/or C15:0 iso 2OH, 11.7%). The polar lipids were sphingoglycolipid, phosphatidyletha-nolamine, phosphatidylglycerol, diphosphatidylglycerol and unidentified glycolipid. Based on the evidence from the polyphasic taxonomic study, the strain should be classified as a new species of the genus Sphingomonas. As a result, the name Sphingomonas jejuensis sp. nov. (type strain MS-31T =KCTC 23321T =NBRC 107775T) is proposed.  相似文献

Three strains of a novel thermophilic, strictly aerobic, Gram-positive, spore-forming hemo-organotrophic bacterium were isolated from three hot springs in the region of Rupi basin, Bulgaria as producers of amylolytic enzymes. Their 16S rRNA gene sequences (first 500 nucleotides) were very similar (99.8%). Strains were able to ferment a wide spectrum of carbohydrates such as sugars, polyols, and polysaccharides like xylan, glycogen and starch. Optimal growth was observed at 55–58°C, and pH at 6.0–6.5. Phylogenetic analysis of the whole 16S rRNA gene sequence clustered the strain R270T with the representatives of the genus Anoxybacillus and with Geobacillus tepidamans. The G + C content of the genomic DNA was 41.7%. DNA–DNA hybridization analysis revealed low homology with the closest relatives (32.0 mol% homology to Geobacillus tepidamans). Fatty acid profile (major fatty acids iso-C15:0 and iso-C17:0) confirmed the affiliation of the strain to the genus Anoxybacillus. On the basis of the data presented here, we propose that strain R270T, represents a new species of the genus Anoxybacillus for which, we recommend the name Anoxybacillus rupiensis sp. nov. (=DSM 17127T = NBIMCC 8387T). The 16S rRNA gene sequence data of a strain R270T have been deposited in the EMBL databases under the accession number AJ879076.  相似文献

A bacterial strain, designated KMM 6244T, was isolated from the sea urchin Strongylocentrotus intermedius and subjected to a polyphasic taxonomic investigation. The bacterium was found to be heterotrophic, aerobic, non-motile and spore-forming. Comparative phylogenetic analysis based on 16S rRNA gene sequencing placed the marine isolate in the genus Bacillus. The nearest neighbor of strain KMM 6244T was Bacillus decolorationis LMG 19507T with a 16S rRNA gene sequence similarity of 98.0%. Sequence similarities with the other recognized Bacillus species were less than 96.0%. The results of the DNA–DNA hybridization experiments revealed a low relatedness (37%) of the novel isolate with the type strain of B. decolorationis LMG 19507T. Strain KMM 6244T grew at 4–45°C and with 0–12% NaCl. It produced catalase and oxidase and hydrolyzed aesculin, casein, gelatin and DNA. The predominant fatty acids were anteiso-C15:0, iso-C15:0, anteiso-C17:0, C15:0, iso-C16:0 and iso-C14:0. The DNA G + C content was 39.4 mol%. A combination of phylogenetic, genotypic and phenotypic data clearly indicated that strain KMM 6244T represents a novel species in the genus Bacillus, for which the name Bacillus berkeleyi sp. nov. is proposed. The type strain is KMM 6244T (KCTC 12718T = LMG 26357T).  相似文献

A Gram-staining-negative, motile, non-spore-forming and rod-shaped bacterial strain, 20-23RT, was isolated from intestine of bensasi goatfish, Upeneus bensasi, and its taxonomic position was investigated by using a polyphasic study. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain 20-23RT belonged to the genus Shewanella. Strain 20-23RT exhibited 16S rRNA gene sequence similarity values of 99.5, 99.2, and 97.5% to Shewanella algae ATCC 51192T, Shewanella haliotis DW01T, and Shewanella chilikensis JC5T, respectively. Strain 20-23RT exhibited 93.1–96.0% 16S rRNA gene sequence similarity to the other Shewanella species. It also exhibited 98.3–98.4% gyrB sequence similarity to the type strains of S. algae and S. haliotis. Strain 20-23RT contained simultaneously both menaquinones and ubiquinones; the predominant menaquinone was MK-7 and the predominant ubiquinones were Q-8 and Q-7. The fatty acid profiles of strain 20–23RT, S. algae KCTC 22552T and S. haliotis KCTC 12896T were similar; major components were iso-C15:0, C16:0, C16:1 ω7c and/or iso-C15:0 2-OH and C17:1 ω8c. The DNA G+C content of strain 20-23RT was 53.9 mol%. Differential phenotypic properties and genetic distinctiveness of strain 20–23RT, together with the phylogenetic distinctiveness, revealed that this strain is distinguishable from recognized Shewanella species. On the basis of the data presented, strain 20-23RT represents a novel species of the genus Shewanella, for which the name Shewanella upenei sp. nov. is proposed. The type strain is 20–23RT (=KCTC 22806T =CCUG 58400T).  相似文献

A novel, Gram-positive bacterium, designated DLS-06T, was isolated from scoria (volcanic ash) under rock on the peak of small mountain (300 m above the sea level; known as Darangshi Oreum) in Jeju, Republic of Korea. The cells of the isolate were aerobic, oxidase-negative, catalase-positive, endospore-forming, non-motile rods. The organism grew at 25∼30°C and initial pH 6.1∼9.1. A neighbour-joining tree based on 16S rRNA gene sequences showed that the organism was related to members of the family “Sporolactobacillaceae” and related taxa. The phylogenetic neighbours were Pullulanibacillus naganoensis (95.2% 16S rRNA gene sequence similarity), Tuberibacillus calidus (95.0%) and Sporolactobacillus (91.8∼94.2%). Levels of 16S rRNA gene sequence similarity of the isolate to representatives of other genera were in the range of 87.2∼93.7%. The organism contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The predominant menaquinone was MK-7. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, an unknown ninhydrin-positive phospholipid, three unknown phospholipids and an unknown lipid. The major fatty acids were anteiso-C15:0 and anteiso-C17:0. The G+C content of the DNA was 50.8 mol%. On the basis of the phenotypic and phylogenetic data presented in this study, this organism represents a novel genus and species in the order Bacillales, for which the name Scopulibacillus darangshiensis gen. nov., sp. nov. is proposed. The type strain is DLS-06T (=DSM 19377T =KCTC 13161T).  相似文献

A bacterial strain, designated Iso4T, was isolated from the East Sea of Korea and was subjected to a poly-phasic taxonomy study including phenotypic and chemotaxonomic characteristics as well as 16S rRNA gene sequence analysis. Cells of the strain were Gram-negative, motile, non-budding, non-stalked, and strictly aerobic. Strain Iso4T grew optimally at 20°C in the presence of 1∼2% (w/v) NaCl and at pH 6.9∼7.6. The major respiratory quinone was Q-10 and the major cellular fatty acids were C18:1 ω7c (53.5%), C17:1 ω5c (11.7%), C17:1 ω6c (8.1%), C16:0 (7.8%), C17:0 (4.8%), C15:0 (2.9%), and C16:1 ω5c (2.2%). The DNA G+C content of strain Iso4T was 56.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Iso4T formed a monophyletic clade in the family Hyphomonadaceae, supported by high bootstrap value and was most closely related to the genus Hyphomonas (92∼94%), a member of marine bacteria in the family. The phenotypic, genotypic, and chemotaxonomic evidences also suggest strain Iso4T represents a novel genus and species in the family Hyphomonadaceae, for which the name Henriciella gen. nov., sp. nov. is proposed. The type strain is Iso4T (=KCTC 12513T =DSM 19595T =JCM 15116T).  相似文献
