A Gram-negative, strictly aerobic, pale-yellow pigmented, rod-shaped bacterium designated A4O-5T was isolated from a red coloured marine alga (Chondrus ocellatus Holmes). Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain was affiliated with the family Flavobacteriaceae and shared approximately 90 % sequence similarity with Leptobacterium flavescens YM3-0301T and Gangjinia marincola GJ16 T. The strain could be differentiated phenotypically from the related members of the family Flavobacteriaceae. The major fatty acids of strain A4O-5T were identified as iso-C15:0, iso-C17:0 3-OH and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c). A complex polar lipid profile was present consisting of phosphatidylethanolamine, an unidentified phospholipid, three unidentified amino lipids and an unidentified lipid. The DNA G+C content of the strain was determined to be 41.9 mol% and the major respiratory quinone was identified as menaquinone 6 (MK-6). From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus in the family Flavobacteriaceae, for which the name Citreitalea marina gen. nov., sp. nov. is proposed. The type strain of C. marina is A4O-5T (=KCTC 32483T=NBRC 109918T). © 2014 Springer International Publishing. Source

A novel Gram-stain negative, spherical, non-motile, strictly aerobic, heterotrophic, yellow pigmented bacterium, designated strain 04OKA003-7T was isolated from the hard coral Galaxea fascicularis L. collected at Akajima, Okinawa, Japan. Phylogenetic analysis based on the 16S rRNA gene sequence revealed the novel isolate is affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (92.9 %) to Vitellibacter aestuarii JC2436T and Aureitalea marina S1-66T. The strain could be differentiated phenotypically from recognized members of the family Flavobacteriaceae. The major fatty acids of strain 04OKA003-7T were identified as iso-C15:0 and iso-C17:0 3-OH as defined by the MIDI system. The DNA G+C content was determined to be 41 mol%, the major respiratory quinone was identified as menaquinone 6 (MK-6) and a polar lipid profile was present consisting of phosphatidylethanolamine, two unidentified aminolipids and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Aureisphaera galaxeae gen. nov., sp. nov. is proposed. The type strain of A. galaxeae is 04OKA003-7T (=KCTC 32993T = NBRC 110018T). © 2015, Springer International Publishing Switzerland. Source

A polyphasic taxonomic investigation was performed on a bacterial strain, 38-Ka-2T, which was isolated from the green alga Ulva pertusa Kjellman (Chlorophyta) in Hokkaido, Japan. The bacterial cells were observed to be golden-yellow coloured, Gram-negative, strictly aerobic, non-spore-forming, non-motile and rod-shaped. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain is a member of the family Flavobacteriaceae within the phylum Bacteroidetes and that it shows high sequence similarity (94.8 %) to Aquimarina addita JC2680T. The genomic DNA G+C content of strain 38-Ka-2T was determined to be 36 mol%; MK-6 was identified as the major menaquinone; and the presence of iso-C15:0, C18:0 and iso-C17:0 3-OH as the major (>10 %) cellular fatty acids. The polar lipid profile was found to consist of phosphatidylethanolamine, an unidentified glycolipid and two unidentified lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, strain 38-Ka-2T is considered to represent a novel genus for which the name Algitalea ulvae gen. nov., sp. nov. is proposed. The type strain of A. ulvae is 38-Ka-2T (=KCTC 32994T = NBRC 110017T). © 2015, Springer International Publishing Switzerland. Source

A Gram-negative, strictly aerobic, reddish-pink-pigmented, non-motile, rod-shaped strain designated A6F-52T was isolated from a lake sediment sample. Preliminary analysis based on the 16S rRNA gene sequence revealed that the novel isolate could be affiliated with the family Catalimonadaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (97.2%) to Catalinimonas alkaloidigena CNU-914T. The level of DNA-DNA relatedness between strains A6F-52T and Catalinimonas alkaloidigena CNU-914T was less than 70%, which is accepted as the phylogenetic definition of a species. The DNA G+C content of strain A6F-52T was 44.4 mol%; MK-7 was the major menaquinone; and the presence of iso-C15: 0, C16: 1 ω5C and iso-C17: 0 3-OH as the major cellular fatty acids supported the identification of the novel isolate as a member of the genus Catalinimonas. A complex polar lipid profile was present consisting of phosphatidylethanolamine, an unidentified phospholipid, and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel species for which the name Catalinimonas niigatensis sp. nov. is proposed. The type strain of Catalinimonas niigatensis is A6F-52T (= KCTC 32474T = NBRC 109829T). © 2014 Applied Microbiology, Molecular and Cellular Biosciences Research Foundation. Source

A Gram-negative, strictly aerobic, lemon-yellow pigmented, non-motile, rod-shaped strain designated A7G-39T was isolated from a yellow coloured marine sponge (Tethya sp.). Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain represented a member of the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (94.1 %) to Algibacter wandonensis WS-MY22T. The strain could be differentiated phenotypically from recognised members of the family Flavobacteriaceae. The major fatty acids of strain A7G-39T were identified as iso-C15:0 3-OH and summed feature 1 (iso-C15:1 H and/or C13:0 3-OH) as defined by the MIDI system. The DNA G+C content was determined to be 32.6 mol%, the major respiratory quinone was identified as menaquinone 7 (MK-7) and a polar lipid profile was present consisting of phosphatidylethanolamine, an unidentified aminolipid and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Spongiivirgacitrea gen. nov. sp. nov. is proposed. The type strain of S.citrea is A7G-39T (=KCTC 32990T = NBRC 110022T). © 2014, Springer Science+Business Media New York. Source
