Abstract

A Gram-stain-negative and facultative aerobic bacterium, strain 16-MA, was isolated from seawater of Yellow Sea in South Korea. Cells were catalase- and oxidase-positive and non-motile rods. Growth occurred at 4–37 °C (optimum, 30 °C) and pH 6.0–11.0 (optimum, 8.0), and in the presence of 0–7.0% NaCl (optimum, 3 %). Strain 16-MA contained ubiquinone-8 as the sole isoprenoid quinone, C and summed feature three as the major fatty acids (>10 %), and phosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid, an unidentified aminophospholipid, and an unidentified polar lipid as the major polar lipids. The genome size and DNA G+C content of strain 16-MA were 3.69 Mb and 46.0 mol%, respectively. Strain 16-MA was most closely related to LNK-7.1 with a 97.9 % 16S rRNA gene sequence similarity. A phylogenomic tree based on whole genome sequences showed that strain 16-MA formed a phylogenetic lineage within the genus . Based on the phenotypic, chemotaxonomic, and molecular analyses, strain 16-MA represents a novel species of the genus , for which the name is proposed. The type strain is 16-MA (=KACC 22238 =JCM 34596).
