Abstract

A Gram-positive, non-motile, rod- or coccoid-shaped -like bacterium, strain DS-3, was isolated from a soil sample from Dokdo, Korea, and its taxonomic position was investigated by a polyphasic approach. The organism grew optimally at 30 °C and pH 7.0–8.0. Strain DS-3 had the peptidoglycan type based on -lys–-Asp, and galactose, glucose, rhamnose and ribose as the whole-cell sugars. It contained MK-9(H) as the predominant menaquinone and anteiso-C and iso-C as the major fatty acids. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two unidentified glycolipids. The DNA G+C content was 74.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-3 was most closely related to members of the genus . Similarity values between the 16S rRNA gene sequences of strain DS-3 and the type strains of species ranged from 98.0 to 98.4 %. DNA–DNA relatedness values (11–23 %) and differential phenotypic properties demonstrated that strain DS-3 was distinguishable from recognized species. On the basis of phenotypic properties and phylogenetic and genetic distinctiveness, strain DS-3 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is DS-3 (=KCTC 19128=CIP 108921).
