Description of Domibacillus iocasae sp. nov., isolated from deep-sea sediment, and emended description of the genus Domibacillus Sun, Qing-Lei and Sun, Li,, 66, 982-987 (2016), doi = https://doi.org/10.1099/ijsem.0.000823, publicationName = Microbiology Society, issn = 1466-5026, abstract= In this study, we report a novel Gram-stain-positive bacterium, designated strain S6T, isolated from deep-sea sediment in Okinawa Trough. Growth of strain S6T occurred at 10–45 °C (optimum, 35 °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 S6T belonged to the genus Domibacillus. The closest phylogenetic neighbours of strain S6T were Domibacillus robiginosus WS 4628T ( = DSM 25058T) (98.6 %16S rRNA gene sequence similarity), D. indicus SD111T ( = DSM 28032T) (97.6 %), D. enclensis NIO-1016T ( = DSM 25145T) (97.6 %), and ‘D. tundrae’ PAMC 80007 ( = DSM 29572) (97.6 %). Levels of similarity between strain S6T and other close relatives were below 96 %. The levels of DNA–DNA relatedness between strain S6T and its closest relatives in the genus Domibacillus were well below 70 %. The genomic DNA G+C content of strain S6T was 44.4 mol%. The major menaquinone was MK-6. The polar lipids of strain S6T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannosides, phosphatidylethanolamine and three unknown phospholipids. Strain S6T harboured meso-diaminopimelic acid as the diagnostic diamino acid and an A1γ type of peptidoglycan. The major cell-wall sugars of strain S6T 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 S6T ( = DSM 29979T = CCTCC AB 2015183T). An emended description of the genus Domibacillus is also provided., language=, type=
