Major Respiratory Quinone

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. The type strain is BOM4T (=MCCC 1K03735T=JCM 33424T).
