摘要In this study, we report a novel Gram-stain-positive bacterium, designated strain S6(T), isolated from deep-sea sediment in Okinawa Trough. Growth of strain S6(T) occurred at 10-45 degrees C (optimum, 35 degrees C), at pH 6.0-11.0 (optimum, 8.0) and with 0-8 % (w/v) NaCl (optimum, 3 %). Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain S6(T) belonged to the genus Domibacillus. The closest phylogenetic neighbours of strain S6(T) were Domibacillus robiginosus WS 4628(T) (=DSM 25058(T)) (98.6 % 16S rRNA gene sequence similarity), D. indicus SD111(T) (=DSM 28032(T)) (97.6 %), D. enclensis NIO-1016(T) (=DSM 25145(T)) (97.6 %), and 'D. tundrae' PAMC 80007 (=DSM 29572) (97.6 %). Levels of similarity between strain S6(T) and other close relatives were below 96 %. The levels of DNA-DNA relatedness between strain S6(T) and its closest relatives in the genus Domibacillus were well below 70 %. The genomic DNA G+C content of strain S6(T) was 44.4 mol%. The major menaquinone was MK-6. The polar lipids of strain S6(T) contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannosides, phosphatidylethanolamine and three unknown phospholipids. Strain S6(T) harboured meso-diaminopimelic acid as the diagnostic diamino acid and an A1 gamma type of peptidoglycan. The major cell-wall sugars of strain S6(T) were xylose and glucose. Phylogenetic, physiological, biochemical and morphological analyses suggest that this strain represents a novel species of the genus Domibacillus, for which the name Domibacillus iocasae sp. nov. is proposed. The type strain is S6(T) (=DSM 29979(T)=CCTCC AB 2015183(T)). An emended description of the genus Domibacillus is also provided.
