A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped, aerobic bacterium, designated 15J9-6T, was isolated from beach soil on Jeju Island, South Korea. Strain 15J9-6T, grew at 10–30°C (optimum growth at 25°C) and pH 7–8 (optimum growth at pH 7) on R2A, NA, and TSA agar. Phylogenetically, the strain was closely related to members of the genus Spirosoma (92.3–90.1% 16S rRNA gene sequence similarities) and showed highest sequence similarity to Spirosoma panaciterrae DSM 21099T (92.3%). The G+C content of the genomic DNA of strain 15J9-6T was 45.7 mol%. The strain contained phosphatidylethanolamine, two unidentified aminophospholipids, an unidentified phospholipid, and an unidentified lipid as the major polar lipids; menaquinone MK-7 as the predominant respiratory quinone and summed feature 3 (C16:1 ω6c/C16:1 ω7c; 30.1%), C16:1 ω5c (23.1%), iso C15:0 (13.3%), and C16:0 (8.4%) as the major fatty acids which supported the affiliation of strain 15J9-6T to the genus Spirosoma. The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 15J9-6T from recognized Spirosoma species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain 15J9-6T represents a novel species of the genus Spirosoma, for which the name Spirosoma daeguensis sp. nov. is proposed. The type strain is 15J9-6T (=KCTC 52036T =JCM 31995T)  相似文献

A Gram-stain-negative and orangish yellow-pigmented bacterial strain, designated PR1014KT, was isolated from an automobile evaporator core collected in Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PR1014KT was related with the members of the genus Spirosoma (94.7–90.2%) and closely related with Spirosoma lacussanchae CPCC 100624T (94.7%), Spirosoma knui 15J8-12T (94.3%), and Spirosoma soli MIMBbqt12T (93.3%). The strain grew at 15–40°C (optimum, 25°C), pH 6.5–7.0 (optimum, 6.5) and 0–1% (w/v) NaCl (optimum, 0%). The predominant fatty acids were summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), C16:0, iso-C15:0, C16:1 ω5c, and iso-C17:0 3-OH. The major menaquinone was MK-7. The polar lipid profile of the strain indicated that the presence of one phosphatidylethanolamine, one unidentified aminolipid, two unidentified aminophospholipids, and three unidentified lipids. The DNA G+C content of the strain was 47.4 mol%. On the basis of the phenotypic, genotypic and chemotaxonomic characteristics, strain PR1014KT represents a novel species in the genus Spirosoma, for which the name Spirosoma metallicus sp. nov. (=KACC 17940T =NBRC 110792T) is proposed.  相似文献

A bacterial strain, K11T, capable of degrading phenol derivatives was isolated from activated sludge of a sewage treatment plant in China. This strain, which can degrade more than ten phenol derivatives, was identified as a Gram-stain negative, rod-shaped, asporogenous, facultative anaerobic bacterium with a polar flagellum. The strain was found to grow in tryptic soy broth in the presence of 0–2.5% (w/v) NaCl (optimum 0–1%), at 4–43 °C (optimum 30–35 °C) and pH 4.5–10.5 (optimum 7.5–8). Comparative analysis of nearly full-length 16S rRNA gene sequences showed that this strain belongs to the genus Thauera. The 16S rRNA gene sequence was found to show high similarity (97.5%) to that of Thauera chlorobenzoica 3CB-1T, with lesser similarity to other recognised Thauera strains. The G+C content of the DNA of the strain was determined to be 67.8 mol%. The DNA–DNA hybridization value between K11T and Thauera aromatica DSM6984T was 10.4 ± 4.5%. The genomic OrthoANI values of K11T with the other nine type strains of genus Thauera were less than 81.1%. Chemotaxonomic analysis of strain K11T revealed that Q-8 is the predominant quinone; the polar lipids contain phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids and five uncharacterised lipids; the major cellular fatty acid was identified as summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH; 45.9%), followed by C16:0 (20.5%) and C18:1 ω7c (15.8%). Based on the phenotypic and phylogenetic evidence, DNA–DNA hybridisation, OrthoANI, chemotaxonomic analysis and results of the physiological and biochemical tests, a new species named Thauera sinica sp. nov. is proposed with strain K11T (= CGMCC 1.15731T = KACC 19216T) designated as the type strain.  相似文献

Strain 63MJ-2T was isolated from the feces of broad-winged katydid (Pseudorhynchus japonicus) collected in Korea. The 16S rRNA gene sequence of this strain showed the highest sequence similarity with that of Siphonobacter aquaeclarae P2T (96.1%) and had low similarities (below 86.3%) with those of other members of family ‘Flexibacteraceae’. The strain 63MJ-2T is a strictly aerobic, Gram-stain-negative, non-motile, rod-shaped bacterium. The strain grew at 4–35°C (optimum, 25–30°C), pH of 5.0–9.0 (optimum, 6.0–7.0), and 0–2.0% (optimum, 1.0–2.0) (w/v) NaCl. The DNA G+C content of strain 63MJ-2T was 43.5 mol%. The major fatty acids were C16:1ω5c (42.5%), iso-C17:0 3-OH (18.7%), and summed feature 3 (iso-C15:0 2-OH and/or C16:1ω7c, 18.0%). The major menaquinone was MK-7 and polar lipids were phosphatidylethanolamine, six unknown aminolipids, and five unknown lipids. Based on the evidence from our polyphasic taxonomic study, we conclude that strain 63MJ-2T should be classified as a novel species of the genus Siphonobacter, and propose the name Siphonobacter intestinalis sp. nov. The type strain is 63MJ-2T (=KACC 18663T =NBRC 111883T).  相似文献

The polar lipids were identified as phosphatidylethanolamine, two unidentified aminophospholipids, an unidentified aminolipid and three unidentified lipids. The quinone was identified as MK-7 and the polyamine as sym-homospermidine. The major fatty acids were identified as C16:1 ω5c, C17:1 ω6c, iso-C15:0, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) and summed feature 4 (iso-C17:1 I and/or anteiso-C17:1 B). On the basis of the phylogenetic analysis, chemotaxonomic data, physiological characteristics, and DNA–DNA hybridization data, strain THG-T16T represents a novel species of the genus Nibribacter, for which the name Nibribacter flagellatus sp. nov. is proposed. The type strain is THG-T16T(=?KACC 19188T?=?CCTCC AB 2016246T).  相似文献

Strain 16F3HT, a Gram-negative, aerobic, non-motile, and oval-shaped bacterium, was isolated from river water collected from the Han River in South Korea. Growth of strain 16F3HT was observed at 10–42 °C (optimum at 25–30 °C), but no growth occurred at 4 °C. The strain is able to grow at pH 4–10 (optimum at pH 7–8) and tolerates up to 4% NaCl (w/v), with optimum growth at 0.5% NaCl. The isolate was found to be resistant to UV irradiation. Based on 16S rRNA gene sequence analysis, it is closely related to ‘Deinococcus seoulensis’ 16F1E (98.8%), Deinococcus aquaticus PB314T (98.1%) and Deinococcus caeni Ho-08T (98.0%). The level of DNA–DNA homology between the novel strain and the three related strains was 57.4, 41.2, and 35.8%, respectively. Chemotaxonomic data revealed that strain 16F3HT possesses MK-8 as the predominant respiratory quinone, an unidentified phosphoglycolipid as the major polar lipid, and C15:1 ω6c and C16:1 ω7c as the major fatty acids. The DNA G + C content was determined to be 65.7 mol%. Based on polyphasic evidence, strain 16F3HT (=KCTC 33794T = JCM 31406T) should be classified as the type strain of a novel Deinococcus species, for which the name Deinococcus knuensis sp. nov. is proposed.  相似文献

A Gram-stain-positive, halophilic, rod-shaped, non-motile, spore forming bacterium, strain NKC1-2T, was isolated from kimchi, a Korean fermented food. Comparative analysis based on 16S rRNA gene sequence demonstrated that the isolated strain was a species of the genus Virgibacillus. Strain NKC1-2T exhibited high level of 16S rRNA gene sequence similarity with the type strains of Virgibacillus xinjiangensis SL6-1T (96.9%), V. sediminis YIM kkny3T (96.8%), and V. salarius SA-Vb1T (96.7%). The isolate grew at pH 6.5–10.0 (optimum, pH 8.5–9.0), 0.0–25.0% (w/v) NaCl (optimum, 10–15% NaCl), and 15–50°C (optimum, 37°C). The major menaquinone in the strain was menaquinone-7, and the main peptidoglycan of the strain was meso-diaminopimelic acid. The predominant fatty acids of the strain were iso-C14:0, anteisio-C15:0, iso- C15:0, and iso-C16:0 (other components were < 10.0%). The polar lipids consisted of diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G + C content of NKC1-2T was 42.5 mol%. On the basis of these findings, strain NKC1-2T is proposed as a novel species in the genus Virgibacillus, for which the name Virgibacillus kimchii sp. nov. is proposed (=KACC 19404T =JCM 32284T). The type strain of Virgibacillus kimchii is NKC1-2T.  相似文献

A Gram-stain negative, aerobic, rod-shaped, non-motile, yellow-pigmented and non-spore-forming bacterial strain, designated PM5-8T, was isolated from a culture of a marine toxigenic dinoflagellate Prorocentrum mexicanum PM01. Strain PM5-8T grew at 15–35 °C (optimum, 25–30 °C) and pH 6–11 (optimum, 7.5–8). Cells required at least 1.5% (w/v) NaCl for growth, and can tolerate up to 7.0% with the optimum of 4%. Phylogenetic analysis based on 16S rRNA gene sequence revealed that the strain PM5-8T is closely related to members of the genus Hoeflea, with high sequence similarities with Hoeflea halophila JG120-1T (97.06%) and Hoeflea alexandrii AM1V30T (97.01%). DNA–DNA hybridization values between the isolate and other type strains of recognized species of the genus Hoeflea were between 11.8 and 25.2%, which is far below the value of 70% threshold for species delineation. The DNA G?+?C content was 50.3 mol%. The predominant cellular fatty acids of the strain were identified as summed feature 8 (C16:1 ω7c and/or C16:1 ω6c; 51.5%), C18:1 ω7c 11-methyl (20.7%), C16:0 (17.2%) and C18:0 (5.7%). The major respiratory quinone was Q-10. Polar lipids profiles contained phosphatidylcholine, phosphatidylglycerol, sulfoquinovosyl diacylglycerol, phosphatidylmono- methylethanolamine, phosphatidylethanolamine and four unidentified lipids. On the basis of the polyphasic taxonomic data presented, strain PM5-8T (=?CCTCC AB 2016294T?=?KCTC 62490T) represents a novel species of the genus Hoeflea, for which the name Hoeflea prorocentri sp. nov. is proposed.  相似文献

A novel pale pink-coloured, strictly aerobic, Gram-stain negative bacterial strain, designated strain KER25-12T, was isolated from a laboratory air-conditioning system in South Korea. Cells were observed to be non-motile cocci showing positive catalase and oxidase reactions. Strain KER25-12T was found to grow at 10–30 °C (optimum, 25–30 °C), at pH 4.0–9.0 (optimum, pH 6.0–7.0) and in the presence of 0–2% (w/v) NaCl (optimum, 0%). Ubiquinone-10 and spermidine were detected as the sole respiratory quinone and the predominant polyamine, respectively. The major fatty acids were identified as summed feature 8 (comprising C18:1 ω7c and/or C18:1 ω6c), summed feature 3 (comprising C16:1 ω7c and/or C16:1 ω6c), C16:0 and C18:0. The genomic DNA G+C content of strain KER25-12T was determined to be 70.0 mol%. The major polar lipids were identified as diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and an unidentified aminolipid. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain KER25-12T belongs to the genus Roseomonas and shows high sequence similarity to Roseomonas aerilata 5420S-30T (98.57%), Roseomonas pecuniae N75T (97.44%) and Roseomonas vinacea CPCC 100056T (97.40%). Based on the morphological, physiological, chemotaxonomic and phylogenetic features, strain KER25-12T is concluded to represent a novel species of the genus Roseomonas, for which the name Roseomonas aeriglobus sp. nov. is proposed. The type strain is KER25-12T (= KACC 19282T = JCM 32049T).  相似文献

A novel Gram-negative and red-pinkish bacterium designated DG5BT was isolated from a dry soil. Cells were rods that were catalase- and oxidase-positive, and non-motile. The strain was found to grow at temperatures from 10 to 30°C (optimum 25°C) and pH 6.0–8.0, (optimum pH 7) on R2A broth. 16S rRNA gene sequence (1,452 bp) analysis of this strain identified it as a member of the genus Hymenobacter that belongs to the class Cytophagia. The highest gene sequence similarities were with Hymenobacter arizonensis OR362-8T (98.3%), Hymenobacter humi DG31AT (97.6%), and Hymenobacter glaciei VUG-A130T (96.6%). Strain DG5BT exhibited <70% DNA-DNA relatedness with H. arizonensis (34.7 ± 7.0%; reciprocally, 29.7 ± 1.2%) and H. humi (39.4 ± 4.3%; reciprocally, 39.5 ± 3.3%) as a different genomic species, and its genomic DNA G+C content was 59.8%. Strain DG5BT had the following chemotaxonomic characteristics: the major fatty acids are iso-C15:0, anteiso-C15:0, C16:1ω5c, and summed feature 3 (C16:1ω7c / C16:1ω6c); polar lipid profile contained phosphatidylethanolamine (PE), unknown aminophospholipid (APL), unknown glycolipids (GL), unknown phospholipids (PL), and unknown polar lipids (L); the major quinone is MK-7. The absorbance peak of pigment is at 481.0 nm. Strain DG5BT showed low-level resistance to gamma-ray irradiation. Phenotypic, chemotaxonomic, and genotypic properties indicated that isolate DG5BT represents a novel species within the genus Hymenobacter for which the name Hymenobacter sedentarius sp. nov. is proposed. The type strain is DG5BT (=KCTC 32524T =JCM 19636T).  相似文献

A bacterial isolate was recovered from a soil sample collected in Jeollabuk-do Province, South Korea, and subjected to polyphasic taxonomic assessment. Cells of the isolate, designated strain S1-2-1-2-1T, were observed to be rod-shaped, pink in color, and Gram-stain negative. The strain was able to grow at temperature range from 10 to 30 °C, with an optimum of 25 °C, and growth occurred at pH 6–8. Comparative 16S rRNA gene sequence analysis showed that strain S1-2-1-2-1T belongs to the genus Hymenobacter, with closely related type strains being Hymenobacter daeguensis 16F3Y-2T (95.8% similarity), Hymenobacter rubidus DG7BT (95.8%), Hymenobacter soli PBT (95.7%), Hymenobacter terrenus MIMtkLc17T (95.6%), Hymenobacter terrae DG7AT (95.3%), and Hymenobacter saemangeumensis GSR0100T (95.2%). The genomic DNA G+C content of strain S1-2-1-2-1T was 63.0 mol%. The main polar lipid of this strain was phosphatidylethanolamine, the predominant respiratory quinone was menaquinone-7, and the major fatty acids were C15:0 iso (27.3%), summed feature 3 (C16:1 ω7c/C16:1 ω6c) (16.5%), C15:0 anteiso (15.3%), and C16:0 (14.7%), supporting the affiliation of this strain with the genus Hymenobacter. The results of this polyphasic analysis allowed for the genotypic and phenotypic differentiation of strain S1-2-1-2-1T from recognized Hymenobacter species. On the basis of its phenotypic properties, genotypic distinctiveness, and chemotaxonomic features, strain S1-2-1-2-1T is considered to represent a novel species of the genus Hymenobacter, for which the name Hymenobacter agri sp. nov. is proposed. The type strain is S1-2-1-2-1T (=KCTC 52739T?=?JCM 32194T).  相似文献

Strain 16F1ET was isolated from a 3-kGy-irradiated sediment sample collected at Han River in Seoul, Republic of Korea. Cells of this strain were observed to be Gram-positive, pililike structure, and short rod shape, and colonies were red in color. The strain showed the highest degree of 16S rRNA gene sequence similarity to Deinococcus aquaticus PB314T (98.8%), Deinococcus depolymerans TDMA-24T (98.1%), Deinococcus caeni Ho-08T (98.0%), and Deinococcus grandis DSM 3963T (97.0%). 16S rRNA gene sequence analysis identified this strain as a member of the genus Deinococcus (Family: Deinococcaceae). The genomic DNA G+C content of strain 16F1ET was 66.9 mol%. The low levels of DNA-DNA hybridization (< 56.2%) with the species mentioned above identified strain 16F1ET as a novel Deinococcus species. Its oxidase and catalase activities as well as the production of acid from glucose were positive. Growth of the strain was observed at 10–37°C (optimum: 20–30°C) and pH 4–10 (optimum: pH 7–8). The cells tolerated less than 5% NaCl and had low resistance to gamma radiation (D10 < 4 kGy). Strain 16F1ET possessed the following chemotaxonomic characteristics: C16:0, C15:1ω6c, and C16:1ω7c as the major fatty acids; phosphoglycolipid as the predominant polar lipid; and menaquinone-8 as the predominant respiratory isoprenoid quinone. Based on the polyphasic evidence, as well as the phylogenetic, genotypic, phenotypic, and chemotaxonomic characterization results, strain 16F1ET (=KCTC 33793T =JCM 31404T) is proposed to represent the type strain of a novel species, Deinococcus seoulensis sp. nov.  相似文献

A moderately halophilic bacterium, designated strain 9-2T, was isolated from saline and alkaline soil collected in Lindian county, Heilongjiang province, China. The strain was observed to be strictly aerobic, Gram-negative, rod-shaped, oxidase-positive, catalase-positive and motile. It was found to require NaCl for growth and to grow at NaCl concentrations of 0.5–14 % (w/v) (optimum, 7–10 %, w/v), at temperatures of 10–45 °C (optimum 25–30 °C) and at pH 5.0–10.0 (optimum pH 8.0). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 9-2T is a member of the genus Halomonas and is closely related to Halomonas desiderata DSM 9502T (96.68 %), Halomonas campaniensis DSM 1293T (96.46 %), Halomonas ventosae DSM 15911T (96.27 %) and Halomonas kenyensis DSM 17331T (96.27 %). The DNA–DNA hybridization value was 38.9 ± 0.66 % between the novel isolate 9-2T and H. desiderata DSM 9502T. The predominant ubiquinones were identified as Q9 (75.1 %) and Q8 (24.9 %). The major fatty acids were identified as C16:0 (22.0 %), Summed feature 8 (C18:1 ω6c/C18:1 ω7c, 19.6 %), Summed feature 3 (C16:1 ω6c/C16:1 ω7c, 12.6 %), C12:0 3-OH (12.0 %) and C10:0 (11.7 %). The DNA G+C content was determined to be 69.7 mol%. On the basis of the evidence presented in this study, strain 9-2T is considered to represent a novel species of the genus Halomonas, for which the name Halomonas heilongjiangensis sp. nov. is proposed. The type strain is 9-2T (=DSM 26881T = CGMCC 1.12467T).  相似文献

A Gram-stain-positive, polar flagella-containing, rod-shaped, obligate aerobic, endospore-forming bacterium, strain TK1655T, was isolated from the traditional Korean food gochujang. The 16S rRNA sequence of strain TK1655T was a member of the genus Oceanobacillus similar to that of the type strain of Oceanobacillus oncorhynchi subsp. incaldanensis DSM 16557T (97.2%), O. oncorhynchi subsp. oncorhynchi JCM 12661T (97.1%), O. locisalsi KCTC 13253T (97.0%), and O. sojae JCM 15792T (96.9%). Strain TK1655T was oxidase and catalase positive. Colonies were circular, smooth, low convex, cream in colour, and measured about 0.5–1.0 mm in diameter. The range for growth was 20–40°C (optimal, 30°C), pH 6.0–10.0 (optimal, 7.0), and 2–16% (w/v) NaCl (optimal, 2%). Additionally, the cells contained meso-DAP, and the predominant isoprenoid quinone was MK-7. The complex polar lipids were consisted of diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylcholine (PC). The major cellular fatty acid components were iso-C15:0, anteiso-C15:0, iso-C16:0, and anteiso-C17:0, and the DNA G+C content was 40.5%. DNA-DNA relatedness of our novel strain and reference strain O. locisalsi KCTC 13253T, O. oncorhynchi subsp. incaldanensis DSM 16557T, O. oncorhynchi subsp. oncorhynchi JCM 12661T was 45.7, 43.8, and 41.9%. From the results of phenotypic, chemotaxonomic, and phylogenetic analyses of strain TK1655T, we propose the novel species Oceanobacillus gochujangensis sp. nov. The type strain is TK1655T (=KCCM 101304T =KCTC 33014T =CIP 110582T =NBRC 109637T).  相似文献

A novel Gram-positive, oval-shaped, non-motile bacterium designated strain 16F1LT was isolated from sediment collected from the Han River in Seoul, Republic of Korea. Based on the 16S rRNA gene sequence (1,448 bp), this strain was identified as a member of the genus Deinococcus that belongs to the class Deinococci. Similarities in the 16S rRNA gene sequence were shown with Deinococcus daejeonensis MJ27T (99.0%), D. grandis DSM 3963T (98.1%), D. radiotolerans C1T (97.5%), and D. caeni Ho-08T (97.2%). Strain 16F1LT was classified as a different genomic species from closely related Deinococcus members, based on less than 70% DNA-DNA relatedness. Genomic DNA G+C content of strain 16F1LT was 67.2 mol%. Strain 16F1LT was found to grow at temperatures of 10–37°C (optimum 25°C) and pH 7–8 (optimum pH 7) on R2A medium, and was catalase-positive and oxidase-negative. Strain 16F1LT showed resistance to gamma radiation (D10 > 2 kGy). In addition, this strain had the following chemotaxonomic characteristics: the major fatty acids were C15:1ω6c and C16:1ω7c; the polar lipid profile contained phosphoglycolipids, unknown aminophospholipids, an unknown aminoglycolipid, unknown aminolipids, an unknown glycolipid, an unknown phospholipid, and an unknown polar lipid; the major quinone was MK-8. Phylogenetic, genotypic, phenotypic, and chemotaxonomic characteristics indicated that strain 16F1LT represents a novel species within the genus Deinococcus, for which the name Deinococcus sedimenti sp. nov. is proposed. The type strain is 16F1LT (=KCTC 33796T =JCM 31405T).  相似文献
