Abstract

A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped or ovoid bacterial strain, designated BG-MY13, was isolated from a tidal flat sediment on the South Sea, South Korea. Strain BG-MY13 grew optimally at 30–35 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain BG-MY13 falls within the cluster comprising the type strains of species of the genus . Strain BG-MY13 exhibited 16S rRNA gene sequ4ence similarity values of 96.9–97.8 % to the type strains of , , and and of 94.6–96.5 % to the type strains of other species of the genus with validly published names. Strain BG-MY13 contained MK-6 as the predominant menaquinone and iso-C and iso-C 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain BG-MY13 was 38.9 mol% and DNA–DNA relatedness values with the type strains of , , and were 12–23 %. The differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain BG-MY13 is separated from other species of the genus . On the basis of the data presented, strain BG-MY13 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is BG-MY13 ( = KCTC 42285 = NBRC 110677).
