A Gram-negative, aerobic, non-flagellated, non-gliding, rod-shaped bacterial strain, designated WR-R1YT, was isolated from soil at a field of reeds in South Korea. Strain WR-R1YT grew optimally at 30 °C, at pH 7.0–7.5 and in the absence of NaCl. Neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain WR-R1YT fell within the clade comprising Mucilaginibacter species, coherently clustering with the type strain of Mucilaginibacter composti, with which it exhibited the highest 16S rRNA gene sequence similarity value of 97.6 %. Sequence similarities to the type strains of the other Mucilaginibacter species and the other species used in the phylogenetic analysis were 93.1–96.9 % and <91.1 %, respectively. Strain WR-R1YT contained MK-7 as the predominant menaquinone and iso-C15:0, summed feature 3 (C16:1 ω6c and/or C16:1 ω7c), C16:0 and iso-C17:0 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine and one unidentified aminophospholipid. The DNA G+C content of strain WR-R1YT was 43.1 mol% and its mean DNA–DNA relatedness value with M. composti KACC 14956T was 17 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain WR-R1YT is separate from other Mucilaginibacter species. On the basis of the data presented, strain WR-R1YT represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter calamicampi sp. nov. is proposed. The type strain is WR-R1YT (= KCTC 32214T = CCUG 63418T).  相似文献

A Gram-stain negative, facultative anaerobic, non-motile, strongly orange-pigmented and rod-shaped bacterium, designated XAY3209T, was isolated from a marine sediment sample collected from the coast of Weihai, China. Strain XAY3209T was found to grow optimally at 30 °C, at pH 7.0 and in the presence of 2.0% (w/v) NaCl. Its genomic DNA G+C content was 41.9 mol%. On the basis of 16S rRNA gene sequence similarity, the novel isolate belongs to the family Cyclobacteriaceae and is related to the genus Algoriphagus. It shares 98.1% 16S rRNA sequence identity with Algoriphagus marincola, its close phylogenetic relative, but did not show similarities more than 97% with other members of the genus Algoriphagus with validly published names. It contained menaquinone-7 (MK-7) as the sole respiratory quinone, iso-C15:0, iso-C17:1 ω9c and Summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH) as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and five unidentified lipids. Results of physiological experiments, biochemical tests and genome average nucleotide identity value (with A. marincola MCCC 1F01203T) indicate that strain XAY3209T is genetically and phenotypically distinct from the species of the genus Algoriphagus with validly published names. Strain XAY3209T therefore represents a novel species, for which the name Algoriphagus formosus sp. nov. is proposed. The type strain is XAY3209T (= KCTC 52842T = MCCC 1H00189T).  相似文献

A Gram-negative, aerobic, rod-shaped, motile, non-spore-forming bacterial strain, designated 13-QT, was isolated from seaside soil under the stacks of the red algae in Hainan province in China. Identification was carried out on the basis of polyphasic taxonomy. Phylogenetic analysis of 16S rRNA gene sequences showed that strain 13-QT belonged to the genus Pedobacter, and the highest similarity was 94.4 % with Pedobacter terricola KCTC 12876T. Strain 13-QT was able to grow at 10–40 °C, in pH 5.0–10.0, in the presence of 0–2.0 % NaCl. The major fatty acids were iso-C15:0 (40.4 %), summed feature 3 (comprising iso-C15:0 2-OH and/or C16:1 ω7c) (18.9 %) and iso-C17:0 3-OH (18.4 %). The predominant menaquinone was MK-7. The G+C content of the genomic DNA was 42.7 mol%. Strain 13-QT could be distinguished from the nearest phylogenetic neighbors by various chemotaxonomic and phenotypic properties. The results of the polyphasic analyses suggested that strain 13-QT should be considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter hainanensis sp. nov. is proposed. The type strain is 13-QT (=CCTCC AB 2012076T = NRRL B-59850T).  相似文献

A Gram-stain negative, non-flagellated, non-gliding, aerobic and rod-shaped bacterium, designated GYSW-15T, was isolated from a seawater of Geoje island on the South Sea, South Korea, and subjected to a polyphasic taxonomic approach. Strain GYSW-15T was found to grow optimally at 30 °C, at pH 7.0–8.0 and in the presence of approximately 2.0 % (w/v) NaCl. Neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain GYSW-15T belongs to the genus Polaribacter, clustering coherently with the type strain of Polaribacter porphyrae showing sequence similarity value of 97.0 %. Strain GYSW-15T exhibited 16S rRNA gene sequence similarity values of 94.3–96.4 % to the type strains of the other Polaribacter species. Strain GYSW-15T was found to contain MK-6 as the predominant menaquinone and iso-C15:0, iso-C15:1 G, iso-C16:0 3-OH and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) as the major fatty acids. The polar lipid profile of strain GYSW-15T containing phosphatidylethanolamine and an unidentified lipid as major components was similar to that of the type strain of P. porphyrae. The DNA G + C content of strain GYSW-15T was determined to be 31.2 mol% and its mean DNA–DNA relatedness with P. porphyrae LMG 26671T was 17 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain GYSW-15T is separated from recognized Polaribacter species. On the basis of the data presented, strain GYSW-15T is considered to represent a novel species of the genus Polaribacter, for which the name Polaribacter marinivivus sp. nov. is proposed. The type strain is GYSW-15T ( = KCTC 42156T = CECT 8655T)  相似文献

A Gram-negative, non-spore-forming, aerobic, non-flagellated, non-gliding and rod-shaped bacterial strain, designated P-R2A1-2T, was isolated from sea squirt (Halocynthia roretzi) collected from the South Sea, Korea. It grew optimally at 25–28 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. Neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that the strain fell within the clade comprising Tenacibaculum species. Strain P-R2A1-2T exhibited the highest 16S rRNA gene sequence similarity values of 97.6, 97.2 and 97.0 % to Tenacibaculum aestuarii SMK-4T, T. lutimaris TF-26T and T. aiptasiae a4T, respectively, and of 94.5–96.8 % to the type strains of the other Tenacibaculum species. Strain P-R2A1-2T contained MK-6 as the predominant menaquinone and C16:1 ω7c and/or iso-C15:0 2-OH, iso-C15:0 3-OH and iso-C15:0 as the major fatty acids. The DNA G + C content of strain P-R2A1-2T was 30.7 mol % and its DNA–DNA relatedness values with the type strains of T. aestuarii, T. lutimaris and T. aiptasiae were 17 ± 4.2, 21 ± 6.1 and 16 ± 5.2 %, respectively. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that the novel strain is separate from other Tenacibaculum species. On the basis of the data presented, strain P-R2A1-2T is considered to represent a novel species of the genus Tenacibaculum, for which the name Tenacibaculum halocynthiae sp. nov. is proposed. The type strain is P-R2A1-2T (=KCTC 32262= CCUG 63681T).  相似文献

Novel orange-pigmented, Gram-negative, rod-shaped, non-motile bacteria, designated strains NIO-S3T and NIO-S4, were isolated from a water sample collected from Cochin back waters, Thanneermukkom and Arookutty, Kerala, India. Both strains were positive for oxidase and catalase activities, and hydrolyzed gelatin and Tween 40. The predominant fatty acids were iso-C15:0, anteiso-C15:0, iso-C17:0 3OH, C16:1ω7c/C16:1ω6c (summed feature 3) and iso-C17:1ω9c/C16:0 10-methyl (summed feature 9), whereas MK-7 was the major respiratory quinone, and phosphatidylethanolamine, two unidentified phospholipids and one unidentified lipid were the only polar lipids. The DNA G+C content of the two strains was 43.7 and 43.6 mol%, respectively. The 16S rRNA gene sequence analysis indicated that they were members of the genus Algoriphagus and closely related to Algoriphagus olei CC-Hsuan-617T, Algoriphagus aquatilis A8-7T, Algoriphagus aquaeductus LMG 24398T and Algoriphagus mannitolivorans DSM 15301T, with pairwise sequence similarities of 96.8, 96.6, 96.2 and 96.2%, respectively. DNA–DNA hybridization between strains NIO-S3T and NIO-S4 showed a relatedness of 89%. Based on data from the current polyphasic study, the strains are proposed as a novel species of the genus Algoriphagus, for which the name Algoriphagus shivajiensis sp. nov. is proposed. The type strain of A. shivajiensis is NIO-S3T (=JCM 17885T = MTCC 11066T).  相似文献

A Gram-negative, aerobic, non-flagellated, non-gliding and rod-shaped bacterial strain, designated M-M16T, was isolated from seashore sand around a seaweed farm on the South Sea, South Korea, and its taxonomic position was investigated by using a polyphasic study. Strain M-M16T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. Strain M-M16T exhibited the highest 16S rRNA gene sequence similarity values to the type strains of Gaetbulibacter lutimaris (96.5 %) and Flaviramulus basaltis (95.8 %). Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain M-M16T clustered with the type strains of Gaetbulibacter species and F. basaltis. Strain M-M16T contained MK-6 as the predominant menaquinone and iso-C15:1 G, iso-C15:0 and iso-C17:0 3-OH as the major fatty acids. The major polar lipids detected in strain M-M16T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain M-M16T was 37.4 mol%. The phylogenetic and chemotaxonomic data and other phenotypic properties revealed that strain M-M16T represents a novel genus and species within the family Flavobacteriaceae, for which the name Sabulilitoribacter multivorans gen. nov., sp. nov. is proposed. The type strain of S. multivorans is M-M16T (= KCTC 32326T = CCUG 63831T).  相似文献

A Gram-stain-negative, non-spore-forming, aerobic, non-flagellated, gliding and rod-shaped bacterial strain, designated HJ-26MT, was isolated from a tidal flat sediment in the Korean peninsula. It grew optimally at 25–30 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that the strain fell within the clade comprising Tenacibaculum species, clustering coherently with the type strains of Tenacibaculum lutimaris and Tenacibaculum aestuarii. Strain HJ-26MT exhibited the highest 16S rRNA gene sequence similarity values of 98.4 and 98.2 % to T. lutimaris TF-26T and T. aestuarii SMK-4T, respectively, and of 94.9–97.4 % to the type strains of the other Tenacibaculum species. Strain HJ-26MT contained MK-6 as the predominant menaquinone and iso-C15:0 and iso-C17:0 3-OH as the major fatty acids. The DNA G+C content of strain HJ-26MT was 34.5 mol% and its mean DNA–DNA relatedness values with the type strains of T. lutimaris and T. aestuarii were 19 and 23 %, respectively. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain HJ-26MT is separate from other Tenacibaculum species. On the basis of the data presented, strain HJ-26MT is considered to represent a novel species of the genus Tenacibaculum, for which the name Tenacibaculum caenipelagi sp. nov. is proposed. The type strain is HJ-26MT (= KCTC 32323T = CECT 8283T).  相似文献

A Gram-negative, aerobic, non-flagellated, non-gliding and rod-shaped bacterial strain, designated WS-MY6T, was isolated from a brown algae reservoir in South Korea. Strain WS-MY6T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain WS-MY6T clustered with the type strains of Algibacter lectus and ‘Algibacter undariae’, showing 16S rRNA gene sequence similarity values of 98.1 and 98.4 %, respectively. It exhibited sequence similarities of 95.4–96.7 % to the type strains of the other Algibacter species, Pontirhabdus pectinovorans and Marinivirga aestuarii, whose reclassification into the genus Algibacter has been recently proposed. Strain WS-MY6T contained MK-6 as the predominant menaquinone and iso-C15:1 G, anteiso-C15:0 and iso-C17:0 3-OH as the major fatty acids. It contained phosphatidylethanolamine and two unidentified lipids as the major polar lipids. The DNA G + C content of strain WS-MY6T was 35.3 mol% and its DNA–DNA relatedness values with A. lectus KCTC 12103T and ‘A. undariae’ WS-MY9T was 21 and 13 %, respectively. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WS-MY6T is separate from existing Algibacter species. On the basis of the data presented, strain WS-MY6T is considered to represent a novel species of the genus Algibacter, for which the name Algibacter miyuki sp. nov. is proposed. The type strain is WS-MY6T (=KCTC 32382T =CECT 8300T).  相似文献

A novel strain, DCY108T was isolated from soil of a Panax ginseng field, Yeoncheon province (38°04′N 126°57′E), Republic of Korea. Strain DCY108T is Gram-negative, non-motile, non-flagellate, rod-shaped, and aerobic. The bacterium grows optimally at 25–30 °C, pH 6.5–7.0 and 1 % NaCl. Phylogenetically, strain DCY108T is closely related to Pedobacter jejuensis JCM 18824T, Pedobacter aquatilis JCM 13454T, Pedobacter kyungheensis LMG 26577T and the type strain of the genus Pedobacter heparinus DSM 2366T. The DNA–DNA relatedness values between strain DCY108T and its close phylogenetic neighbors were below 30.0 %. The DNA G+C content of strain DCY108T was determined to be 45.1 mol%. The predominant quinone was menaquinone 7 (MK-7). The major polar lipids were identified as phosphatidylethanolamine and three unidentified aminolipids AL1, AL13 and AL17. Iso-C15:00, iso-C17:03OH and summed feature 3 (C16:1 ω7c/C16:1 ω6c) were identified as the major fatty acids present in strain DCY108T. The results of physiological and biochemical tests allowed strain DCY108T to be differentiated phenotypically from other recognized species belonging to the genus Pedobacter. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Pedobacter panacis sp. nov is proposed with the type strain designated as DCY108T (=CCTCCAB 2015196T = KCTC 42748T).  相似文献

A non-pigmented, motile, Gram-negative bacterium designated H 17T was isolated from a seawater sample collected in Port Phillip Bay (the Tasman Sea, Pacific Ocean). The new organism displayed optimal growth between 4 and 37 °C, was found to be neutrophilic and slightly halophilic, tolerating salt water environments up to 10 % NaCl. Strain H 17T was found to be able to degrade starch and Tween 80 but unable to degrade gelatin or agar. Phosphatidylglycerol (27.7 %) and phosphatidylethanolamine (72.3 %) were found to be the only associated phospholipids. The major fatty acids identified are typical for the genus Alteromonas and include C16:0, C16:1ω7, C17:1ω8 and C18:1ω7. The G+C content of the DNA was found to be 43.4 mol%. A phylogenetic study, based on the 16S rRNA gene sequence analysis and Multilocus Phylogenetic Analysis, clearly indicated that strain H 17T belongs to the genus Alteromonas. The DNA?DNA relatedness between strain H 17T and the validly named Alteromonas species was between 30.7 and 46.4 mol%. Based on these results, a new species, Alteromonas australica, is proposed. The type strain is H 17T (= KMM 6016T = CIP 109921T).  相似文献

A novel bacterium designated S-42T was isolated from stream bank soil. Cells were found to be aerobic, Gram staining-negative, oxidase-positive, catalase-negative, non-motile, non-spore-forming, rod-shaped, and yellow-pigmented. The strain can grow at 15–35 °C, pH 6.0–10.0, and at 0.5% (w/v) NaCl concentration. Urea was hydrolysed. Flexirubin-type pigments were absent. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain S-42T formed a lineage within the family Flavobacteriaceae of the phylum Bacteroidetes that is distinct from various species of the genus Flavobacterium, including Flavobacterium maotaiense T9T (97.6% sequence similarity), Flavobacterium hibernum ATCC 51468T (97.4%), and Flavobacterium granuli Kw05T (97.1%). The 16S rRNA gene sequences identity between strain S-42T and other members of the genus Flavobacterium were < 97.0%. Strain S-42T contains MK-6 as sole respiratory quinone. The major polar lipids were identified as phosphatidylethanolamine and an unidentified aminolipid. The major cellular fatty acids were identified as iso-C15:0, summed feature 3 (C16:1ω7c and/or C16: 1ω6c), C16:0, anteiso-C15:0, iso-C17:0 3-OH, iso-C15:0 3-OH, and iso-C15:1 G. The DNA G?+?C content of the strain was 35.8 mol%. The polyphasic characterization indicated that strain S-42T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium ureilyticum sp. nov. is proposed. The type strain is S-42T (=?KEMB 9005-537T?=?KACC 19115T?=?NBRC 112683T).  相似文献

A Gram-negative, aerobic, non-motile and ovoid or rod-shaped bacterial strain, GGW-M5T, was isolated from seawater on the southern coast in Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain GGW-M5T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain GGW-M5T belonged to the genus Glaciecola, joining the cluster comprising the type strains of G. agarilytica, G. arctica, G. chathamensis, G. mesophila, G. polaris and G. psychrophila, with which it exhibited 16S rRNA gene sequence similarity values of 95.9–96.7 %. Strain GGW-M5T exhibited sequence similarity values of 93.2–94.8 % to the type strains of the other Glaciecola species. Strain GGW-M5T contained Q-8 as the predominant ubiquinone and C16:1 ω7c and/or iso-C15:0 2-OH, C16:0 and C14:0 2-OH as the major fatty acids. Major polar lipids were phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol. The DNA G+C content was 42.4 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain GGW-M5T could be distinguished from other Glaciecola species. On the basis of the data presented, strain GGW-M5T is considered to represent a novel species of the genus Glaciecola, for which the name Glaciecola aquimarina sp. nov. is proposed. The type strain is GGW-M5T (=KCTC 32108T = CCUG 62918T).  相似文献

A Gram-negative, facultatively anaerobic, non-motile and rod-shaped bacterial strain, designated SMK1-12T, was isolated from a tidal flat sediment on the western coast of Korea. Phylogenetic analyses based on 16S rRNA and gyrB gene sequences showed that strain SMK1-12T belonged to the genus Shewanella, clustering with the type strain of Shewanella amazonensis. Strain SMK1-12T exhibited the highest 16S rRNA gene sequence similarity value (97.0 %) and the highest gyrB sequence similarity value (87.8 %) to S. amazonensis SB2BT, respectively. Strain SMK1-12T contained simultaneously both menaquinones and ubiquinones; the predominant menaquinone was MK-7 and the predominant ubiquinones were Q-7 and Q-8. The major fatty acids (>10 % of the total fatty acids) detected in strain SMK1-12T were the MIDI system summed feature 3 (iso-C15:0 2-OH and/or C16:1 ω7c), iso-C15:0, C17:1 ω8c and C16:0. The DNA G+C content of strain SMK1-12T was 58.0 mol% and its mean DNA–DNA relatedness value with S. amazonensis ATCC 700329T was 15 ± 4.6 %. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain SMK1-12T is distinguishable from recognized Shewanella species. On the basis of the data presented, strain SMK1-12T is considered to represent a novel Shewanella species, for which the name Shewanella litorisediminis sp. nov. is proposed. The type strain is SMK1-12T (=KCTC 23961T = CCUG 62411T).  相似文献

A Gram-positive, coccoid to rod-shaped, non-spore-forming bacterium, designated Gsoil 958T, was isolated from soil of a ginseng field located in Pocheon province in South Korea. This bacterium was characterized in order to determine its taxonomic position by using a polyphasic approach. Strain Gsoil 958T was observed to grow well at 25–30 °C and at pH 7.0 on R2A and nutrient agar without NaCl supplementation. Strain Gsoil 958T was determined to have β-glucosidase activity and the ability to transform ginsenoside Rb1 (one of the dominant active components of ginseng) to F2 via gypenoside XVII and Rd. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 958T was shown to belong to the family Nocardioidaceae and related most closely to Nocardioides koreensis MSL-09T (97.6 % 16S rRNA gene sequence similarity), Nocardioides aquiterrae GW-9T (97.0 %), and Nocardioides sediminis MSL-01T (97.0 %). The sequence similarities with other validly named species within the genus Nocardioides were less than 96.8 %. Strain Gsoil 958T was characterized chemotaxonomically as having LL-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone, and iso-C16:0, iso-C16:1 H, iso-C14:0, iso-C15:0 were identified as the major fatty acids. The G + C content of genomic DNA was determined to be 70.8 mol %. The chemotaxonomic properties and phenotypic characteristics supported the affiliation of strain Gsoil 958T to the genus Nocardioides. The results of both physiological and biochemical tests allowed for differentiation of strain Gsoil 958T from the recognized Nocardioides species. Therefore, strain Gsoil 958T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides panaciterrulae sp. nov. is proposed, with the type strain Gsoil 958T (KACC 14271T = KCTC 19471T = DSM 21350T).  相似文献
