A Gram-stain-negative, strictly aerobic, non-flagellated, rod-shaped bacterium, designated GSB7
T , was isolated from seawater collected at the Yellow Sea coast of South Korea. Catalase and oxidase activities were positive. Growth occurred at pH 6.0–9.0 (optimum pH 7.0), 10–40 °C (optimum 30 °C) and with 0–8% NaCl (optimum 1–2%). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain GSB7T belonged to the genus Marivivens, showing the sequence similarities of 96.3, 96.1, and 96.0% with Marivivens niveibacter HSLHS2T , Limimaricola hongkongensis DSM17492T , and Marivivens donghaensis AM-4T , respectively. The respiratory quinone was ubiquinone-10 and the major fatty acids were summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), C18:1 ω7c 11-methyl, C16:0 and C10:0 3-OH. The polar lipids comprised phosphatidylglycerol, diphosphatidylglycerol, one unidentified aminolipid, and five unidentified lipids. The DNA G + C content calculated from the whole-genome sequence was 60.6 mol%. On the basis of phenotypic, chemotaxonomic and genotypic characteristics presented in this study, strain GSB7T is suggested to represent a novel species of the genus Marivivens, for which the name Marivivens aquimaris sp. nov. is proposed. The type strain is GSB7T (= KCTC 82026T = JCM 34042T ). [ABSTRACT FROM AUTHOR]- Published
