A Gram-positive, rod-shaped or coccoid bacterial strain, DS-51T, was isolated from a soil in Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain DS-51T grew optimally at pH 8.0 and 30°C without NaCl. Phylogenetic analyses based on 16S rRNA qene sequences showed that strain DS-51T forms a distinct line of descent within the radiation enclosed by the genus Nocardioides. The chemotaxonomic properties of strain DS-51T were consistent with those of the genus Nocardioides: the cell-wall peptidoglycan type was based on LL-2,6-diaminopimelic acid, MK-8(H4) was the predominant menaquinone and iso-C16:0 was the major fatty acid. The DNA G+C content was 71.1 mol%. The 16S rRNA gene sequence of strain DS-51 T had similarity levels of 92.5-95.1 % with the sequences of the type strains of Nocardioides species. Strain DS-51T could be distinguished from other Nocardioides species by differences in some phenotypic characteristics. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain DS-51T represents a novel species of the genus Nocardioides, for which the name Nocardioides insulae sp. nov. is proposed. The type strain is DS-51T (=KCTC 19180T = DSM 17944T).
