A Gram-positive, non-motile, cream-coloured, curved or straight rod-shaped bacterial strain, DS-10, was isolated from soil of Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain DS-10 grew optimally at 25 °C and pH 7.0–8.0 in the presence of 0.5–1.0 % (w/v) NaCl. Strain DS-10 had peptidoglycan type B2 [-Glu–-Dab (diaminobutyric acid)] and galactose and ribose as whole-cell sugars. Strain DS-10 contained MK-11, MK-12 and MK-10 as predominant menaquinones. Major cellular fatty acids (>10 % of total) were anteiso-C, anteiso-C, iso-C and iso-C. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid. The DNA G+C content was 71.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-10 belonged to the genus . Similarity values between the 16S rRNA gene sequence of strain DS-10 and those of the type strains of recognized species ranged from 95.8 to 99.3 %. DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain DS-10 could be differentiated from recognized species. On the basis of the data presented, strain DS-10 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DS-10 (=KCTC 19216 =JCM 14581).
