Physiological And Biochemical

A Gram-staining-positive, motile, rod-shaped, spore-forming bacterium, designated P9T, was isolated from soil in Portugal. This organism was aerobic and catalase- and oxidase-positive. It had an optimum growth temperature of about 35 °C and an optimum growth pH of about 8.0–8.5, and grew in medium with 0–9 % (w/v) NaCl. The cell-wall peptidoglycan was of the A1α type, with l-lysine as the diagnostic diamino acid. The major respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were anteiso-C15 : 0 (45.4 %), iso-C15 : 0 (22.0 %) and anteiso-C17 : 0 (11.2 %). The genomic DNA G+C content was about 39.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain P9T was most closely related to Jeotgalibacillus campisalis DSM 18983T (96.8 %) and Jeotgalibacillus marinus DSM 1297T (96.5 %). These two recognized species formed a coherent cluster with strain P9T that was supported by a bootstrap value of 99 %. On the basis of the phylogenetic analysis and physiological and biochemical characteristics, strain P9T ( = DSM 23228T = LMG 25523T) represents a novel species of the genus Jeotgalibacillus, for which the name Jeotgalibacillus soli sp. nov. is proposed.

Strains TU-16T and TU-18, two non-pigmented bacterial isolates with an optimum growth temperature of about 45 °C and an optimum pH of about 8·5–9·0, were recovered from the Furnas geothermal area on the Island of São Miguel in the Azores. Phylogenetic analysis of the 16S rRNA gene sequence of these strains indicated that they represent a novel species in a new genus of the phylum Betaproteobacteria. The major fatty acids of strains TU-16T and TU-18 were 16 : 0 and 18 : 1ω7c. Ubiquinone 8 was the major respiratory quinone and the major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The novel isolates were aerobic; thiosulfate was oxidized to sulfate in the presence of a metabolizable carbon source. The organism assimilated organic acids and amino acids, but did not assimilate carbohydrates or polyols. Based on phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strain TU-16T (=LMG 23030T=CIP 108724T) represents the type strain of a novel species in a new genus, Tepidicella xavieri gen. nov., sp. nov.

The 16S Rrna Gene

Two moderately halophilic Gram-negative bacteria were isolated from a sample taken from the brine–seawater interface of the Shaban Deep in the Red Sea. Phylogenetic analysis of the 16S rRNA gene sequence showed that these organisms represent a novel species of the genus Marinobacter. Cells of the new isolates formed non-pigmented colonies and were motile by means of a single polar flagellum. Strains SD-14BT and SD-14C grew optimally at 35–37 °C, in 5 % NaCl and at pH 7.5–8.0. The organisms were aerobic, but reduced nitrate to nitrogen under anaerobic conditions. Acid was produced from only a few carbohydrates. Ubiquinone 9 was the major respiratory quinone. The major fatty acids of strains SD-14BT and SD-14C were C16 : 0, C18 : 1 ω9c, summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c) and C12 : 0 3-OH. The DNA G+C contents were 55.9 and 55.7 mol%, respectively. On the basis of the phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strains SD-14BT and SD-14C represent a novel species of the genus Marinobacter, with the name Marinobacter salsuginis sp. nov. The type strain is strain SD-14BT (=DSM 18347T=LMG 23697T).

A bacterial isolate, with an optimum growth temperature of about 50 °C and an optimum pH for growth between 7.5 and 8.5, was recovered from a hot spring in the Furnas area of the Island of São Miguel in the Azores. The novel isolate is orange-pigmented, forms non-motile, rod-shaped cells that stain Gram-negative, is strictly aerobic, oxidase-positive and catalase-negative. The major fatty acids of strain TU-20T are 16 : 1ω6c, 17 : 0 iso 3-OH and 15 : 0 iso. Menaquinone 6 is the major respiratory quinone. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics, we describe a novel species of a novel genus represented by strain TU-20T ( = DSM 21410T  = LMG 24594T) for which we propose the name Schleiferia thermophila gen nov., sp. nov. We also propose the family Schleiferiaceae fam. nov. to accommodate this new genus.

Two Gram-staining-negative, rod-shaped, non-spore-forming bacterial strains, 1-2T and 1-4 were isolated from dry riverbed soil collected from the Xietongmen area of Tibet, China. On the basis of 16S rRNA gene sequence similarity, the novel strains were shown to belong to the genus Pedobacter, sharing <95 % sequence similarity with all recognized species of the genus Pedobacter. The major respiratory quinone was MK-7 and the predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising iso-C16 : 1 ω7c and/or C16 : 1 ω6c). The DNA G+C contents were 37.2–37.6 mol%. Chemotaxonomic data supported the affiliation of the two new isolates to the genus Pedobacter and the results of physiological and biochemical tests confirmed that the new strains differed significantly from the recognized species of the genus Pedobacter. Therefore, the new isolates represent a novel species within the genus Pedobacter, for which the name Pedobacter glucosidilyticus sp. nov. is proposed. The type strain is 1-2T (=CCTCC AB 206110T=KCTC 22438T).

Sequence Similarities

A yellow-pigmented, Gram-staining-negative, non-motile, strictly aerobic and rod-shaped bacterium, designated CS100T, was isolated from soil in Chungbuk, Korea. Phylogenetic analysis and comparative studies based on the 16S rRNA gene sequence showed that strain CS100T belonged to the genus Flavobacterium in the family Flavobacteriaceae. Strain CS100T showed the highest sequence similarities to Flavobacterium glaciei JCM 13953T (97.6 %) and Flavobacterium johnsoniae KACC 11410T (97.1 %). Sequence similarity to other members of the genus Flavobacterium was 91.5–97.0 %. Growth occurred at 4–30 °C, at pH 5.0–9.0 and in the presence of 0–2 % (w/v) NaCl. Flexirubin-type pigments were produced. Menaquinone-6 (MK-6) was the major respiratory quinone and the major fatty acids were iso-C15 : 0 (17.3 %), summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c, 15.5 %) and C16 : 0 (11.8 %). The DNA G+C content was 36.4 mol%. Strain CS100T hydrolysed skimmed milk and gelatin, but not chitin or pectin, and showed oxidase and catalase activities. DNA–DNA relatedness was 3.0 % with F. glaciei JCM 13953T and 11.5 % with F. johnsoniae KACC 11410T. On the basis of the evidence from this study, strain CS100T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium chungbukense sp. nov. is proposed. The type strain is CS100T ( = KACC 15048T = JCM 17386T).

A Gram-staining-negative, non-motile, yellow-coloured, rod-shaped bacterium, designated S44T, was isolated from bankside soil of Xixi wetland, located in Zhejiang province, China. Growth of strain S44T was observed at 6–37 °C (optimum, 28 °C) and at pH 6.0–9.0 (optimum, 7.0). No growth occurred in the presence of >2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain S44T represented a member of the genus Flavobacterium , showing the highest sequence similarities to the sequences from Flavobacterium succinicans DSM 4002T (96.9 %), Flavobacterium reichenbachii WB 3.2-61T (96.6 %) and Flavobacterium glycines NCBI 105008T (96.5 %). The G+C content of the genomic DNA was 33.6 mol%. The predominant cellular fatty acids were C15 : 0, iso-C15 : 0, anteiso-C15 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), and the major respiratory quinone was menaquinone 6 (MK-6). The major polar lipids were phosphatidylethanolamine, two unknown aminolipids, two unknown aminophospholipids and four unknown polar lipids. On the basis of the phenotypic and genotypic data, it is proposed that the isolate S44T be classified as representing a novel species of the genus Flavobacterium , for which the name Flavobacterium palustre sp. nov. is proposed. The type strain is S44T ( = CGMCC 1.12811T = NBRC 110389T).

A yellow-coloured bacterial strain, designated HB2T, isolated from stratum water was investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was a member of the genus Luteimonas , its three closest neighbours being Luteimonas aquatica BCRC 17731T (97.5 % similarity), Luteimonas marina JCM 12488T (97.3 %) and Luteimonas aestuarii DSM 19680T (96.9 %). Strain HB2T could clearly be distinguished from these type strains based on phylogenetic analysis, DNA–DNA hybridization, fatty acid composition and a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strain HB2T represents a novel species of the genus Luteimonas , for which the name Luteimonas huabeiensis sp. nov. is proposed. The type strain is HB2T ( = DSM 26429T = CICC 11005sT).

Two facultatively anaerobic bacterial strains, designated WR061T and WR054, were isolated from rice-straw residue in a methanogenic reactor treating waste from cattle farms in Japan. The two strains were phylogenetically positioned close to one another and had almost the same phenotypic properties. Cells were Gram-reaction-positive, non-motile, non-spore-forming, irregular rods. Cobalamin (vitamin B12) was required for growth. The strains utilized various carbohydrates, including hexoses and disaccharides, and produced acetate and propionate from these carbohydrates. Pentoses and polysaccharides were not utilized. They grew at 20–37 °C (optimum 35 °C) and pH 5.3–8.0 (optimum pH 6.8–7.5). Catalase and nitrate-reducing activities were detected. Aesculin was hydrolysed. The major cellular fatty acids were anteiso-C15 : 0 and C15 : 0 DMA, the major respiratory quinone was menaquinone MK-9(H4) and the genomic DNA G+C content was 69.3–69.5 mol%. The diagnostic diamino acid in the peptidoglycan was meso-diaminopimelic acid. Phylogenetic analysis based on 16S rRNA gene sequences placed the strains in the phylum Actinobacteria. Both strains were remotely related to the species in the family Propionibacteriaceae and Propionibacterium propionicum JCM 5830T was the most closely related type strain with a sequence similarity of 91.6 %. Based on phylogenetic, physiological and chemotaxonomic analyses, the two novel strains together represent a novel species of a new genus, for which the name Propioniciclava tarda gen. nov., sp. nov. is proposed. The type strain is WR061T ( = JCM 15804T  = DSM 22130T).

Sequence Similarities

A rod-shaped Gram-staining-negative, non-motile, aerobic and fucoidan-digesting strain, designated TC2T, was isolated from marine algae collected from the coast of the Sea of Okhotsk at Abashiri, Hokkaido, Japan. The bacterium formed yellow, translucent, circular and convex colonies. Comparative 16S rRNA gene sequence analysis indicated that the strain belonged to the genus Flavobacterium, with the highest sequence similarities of 97.1 to 97.3 % to the type strains of Flavobacterium frigidarium, Flavobacterium frigoris, Flavobacterium limicola and Flavobacterium psychrolimnae. DNA–DNA relatedness values between strain TC2T and the above-mentioned species were lower than 28 %. The genomic DNA G+C content was 33.9 mol%. The major respiratory quinone was menaquinone-6 and the predominant fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C15 : 0 3-OH and summed feature 3 (which comprises iso-C15 : 0 2-OH and/or C16 : 1 ω7c). Strain TC2T could be differentiated from related species by several phenotypic characteristics. Thus, on the basis of these results, strain TC2T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium algicola sp. nov. is proposed. The type strain is TC2T (=NBRC 102673T =CIP 109574T).

Two yellow bacterial strains, designated NBD5T and NBD8, isolated from Noni (Morinda citrifolia L.) branch were investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-motile and short rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences suggested that the strains were members of a novel species of the genus Sphingomonas, the seven closest neighbours being Sphingomonas oligoaromativorans SY-6T (96.9  % similarity), Sphingomonas polyaromaticivorans B2-7T (95.8  %), Sphingomonas yantingensis 1007T (94.9  %), Sphingomonas sanguinis IFO 13937T (94.7  %), Sphingomonas ginsenosidimutans Gsoil 1429T (94.6  %), Sphingomonas wittichii RW1T (94.6  %) and Sphingomonas formosensis CC-Nfb-2T (94.5  %). Strains NBD5T and NBD8 had sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine as the major polar lipids, ubiquinone 10 as the predominant respiratory quinone, and sym-homospermidine as the major polyamine. Strains NBD5T and NBD8 were clearly distinguished from reference type strains based on phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data analysis, and comparison of a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strains NBD5T and NBD8 represent a novel species of the genus Sphingomonas, for which the name Sphingomonas morindae sp. nov. is proposed. The type strain is NBD5T ( = DSM 29151T = KCTC 42183T = CICC 10879T).
