Abstract

A Gram-stain-negative, aerobic, non-flagellated and rod-shaped or ovoid bacterial strain, designated GJSW-36, was isolated from seawater at Geoje island in the South Sea, South Korea. Strain GJSW-36 grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain GJSW-36 fell within the clade comprising the type strains of species of the genus and . Strain GJSW-36 exhibited 16S rRNA gene sequence similarity values of 94.2–96.0 % to the type strains of species of the genus and and of 93.8–94.5 % to the type strains of the other species of the genus . Strain GJSW-36 contained ubiquinone-8 (Q-8) as the predominant ubiquinone and summed feature 3 (Cω7 and/or Cω6), Cω8 and C as the major fatty acids. The major polar lipids of strain GJSW-36 were phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content of strain GJSW-36 was 45.1 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain GJSW-36 is separated from species of the genus and . On the basis of the data presented, strain GJSW-36 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is GJSW-36 ( = KCTC 42155 = CECT 8656). From this study, it is also proposed that should be reclassified as a member of the genus and the description of the genus is emended.
