A novel psychrophilic, marine, bacterial strain designated BJ-1T was isolated from the Iheya North hydrothermal field in the Okinawa Trough off Japan. Cells were Gram-negative, rod-shaped, non-spore-forming, aerobic chemo-organotrophs and motile by means of a single polar flagellum. Growth occurred at temperatures below 16 °C, with the optimum between 9 and 12 °C. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the closest relatives of strain BJ-1T were Shewanella denitrificans OS-217T (93.5 % similarity), Shewanella profunda DSM 15900T (92.9 %), Shewanella gaetbuli TF-27T (92.9 %), Paraferrimonas sedimenticola Mok-106T (92.1 %) and Ferrimonas kyonanensis Asr22-7T (91.7 %). The major respiratory quinone was Q-8. The predominant fatty acids were C16 : 1ω7c and C16 : 0. The G+C content of the novel strain was 40.5 mol%. Based on phylogenetic, phenotypic and chemotaxonomic evidence, it is proposed that strain BJ-1T represents a novel species in a new genus, for which the name Psychrobium conchae gen. nov., sp. nov. is proposed. The type strain of Psychrobium conchae is BJ-1T ( = JCM 30103T = DSM 28701T).

Bacterium Strain

A Gram-stain-negative, strictly aerobic, motile by gliding, rod-shaped and non-flagellated marine bacterium strain, designated BOM4T, was isolated from a mussel inhabiting the Tangyin hydrothermal field of the Okinawa Trough. The growth temperature was in the range of 16–40 °C, and the optimum temperature was 37 °C. Optimal growth occurred at pH 7.0 and in the presence of 1 % (w/v) NaCl. The predominant isoprenoid quinone of strain BOM4T was identified as menaquinone-6 (MK-6). The predominant fatty acids (>10 %) were iso-C15 : 0(43.8 %) and iso-C17 : 0 3-OH (17.5 %). The major polar lipids comprised one phosphatidylethanolamine, three unidentified aminolipids and two unidentified lipids. Based on 16S rRNA gene sequence analyses, strain BOM4T was found to be most closely related to Gramella aestuarii JCM 17790T (96.7 %), followed by Gramella flava JLT2011T (96.1 %), Gramella sediminilitoris GHTF-27T (95.6 %) and Gramella gaetbulicola RA5-111T (95.5 %) and with lower sequence similarities (93.7- 95.4 %) to other species of the genus Gramella . Genome relatedness between strain BOM4T and G. aestuarii JCM 17790T was computed using both average nucleotide identity and DNA–DNA hybridization with values of 75.6 and 19.3±2.4 %, respectively. The DNA G+C content of strain BOM4T was 41.4 mol%. On the basis of polyphasic analysis, strain BOM4T was considered to represent a novel species of the genus Gramella , for which the name Gramella bathymodioli sp. nov. is proposed.

A novel species of Fe(III)-reducing bacterium, designated strain OSK6T, belonging to the genus Geobacter , was isolated from lotus field mud in Japan. Strain OSK6T was isolated using a solid medium containing acetate, Fe(III)-nitrilotriacetate (NTA) and gellan gum. The isolate is a strictly anaerobic, Gram-negative, motile, straight rod-shaped bacterium, 0.6–1.9 µm long and 0.2–0.4 µm wide. The growth of the isolate occurred at 20–40 °C with optima of 30–37 °C and pH 6.5–7.5 in the presence of up to 0.5 g NaCl l−1. The G+C content of the genomic DNA was determined by HPLC to be 59.7 mol%. The major respiratory quinone was MK-8. The major fatty acids were 16 : 1ω7c and 16 : 0. Strain OSK6T was able to grow with Fe(III)-NTA, ferric citrate, amorphous iron (III) hydroxide and nitrate, but not with fumarate, malate or sulfate as electron acceptors. Among examined substrates grown with Fe(III)-NTA, the isolate grew on acetate, lactate, pyruvate and succinate. Analysis of the near full-length 16S rRNA gene sequence revealed that strain OSK6T is closely related to Geobacter daltonii and Geobacter toluenoxydans with 95.6 % similarity to the type strains of these species. On the basis of phylogenetic analysis and physiological tests, strain OSK6T is described as a representative of a novel species, Geobacter luticola sp. nov.; the type strain is OSK6T ( = DSM 24905T = JCM 17780T).

A Gram-stain-negative, orange-pigmented and strictly aerobic bacterium, designated strain MJ115T, was isolated from seawater in Pohang, South Korea. Cells were non-motile rods and showed positive reactions for catalase and oxidase tests. Growth of strain MJ115T was observed at 4–35 °C (optimum, 30 °C), pH 6.0–7.0 (optimum, pH 6.5) and in the presence of 0–8.0 % (w/v) NaCl (optimum, 2.0%). Strain MJ115T contained iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 1  ω9c, C17 : 0 2-OH, iso-C16 : 0 3-OH, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) as major cellular fatty acids and menaquinone-6 as the major respiratory quinone. Phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids were detected as major polar lipids. The G+C content of the genomic DNA was 40.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ115T formed a phyletic lineage with Nonlabens marinus S1-08T, Nonlabens agnitus JC2678T and Nonlabens antarcticus AKS 622T within the genus Nonlabens . Strain MJ115T was also most closely related to N. marinus S1-08T, N. agnitus JC2678T and N. antarcticus AKS 622T with 96.5, 96.4 and 96.0 % 16S rRNA sequence similarities, respectively. Here it is proposed that strain MJ115T represents a new species of the genus Nonlabens , for which the name Nonlabens ponticola sp. nov. is proposed. The type strain is MJ115T (=KCTC 72237T=NBRC 113963T). In addition, the comparison of the whole genome sequences and phenotypic features suggested that Nonlabens tegetincola and Nonlabens sediminis belong to the same species. Therefore, it is proposed that N. sediminis is reclassified as a later heterotypic synonym of N. tegetincola .
