A Gram-negative marine bacterium, designated strain En6T, was isolated from seawater of the East Sea of Korea. The organism grew in 1–25 % (w/v) NaCl and at 10–37 °C and pH 5.3–9.3, with optimal growth occurring in 4–5 % NaCl and at 25–30 °C and pH 7.5. Phylogenetic analysis of the 16S rRNA gene sequence of strain En6T placed this bacterium in the clade Marinobacter within the class Gammaproteobacteria. The 16S rRNA gene sequence similarity between strain En6T and Marinobacter lipolyticus SM19T, the most closely related species, was 98.4 %, and the level of DNA–DNA relatedness between the two strains was 22 %. On the basis of the phylogenetic analysis and phenotypic and chemotaxonomic data, strain En6T is considered to represent a novel species of the genus Marinobacter. The name Marinobacter goseongensis sp. nov. is proposed, with strain En6T (=KCTC 12515T=DSM 19471T) as the type strain.
