Abstract
A short coccoid-rod-shaped, nonmotile actinobacteria strain MSL-11T was isolated from soil in Bigeum Island, Korea. A polyphasic study was undertaken to establish the taxonomic position of this strain. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain MSL-11T forms an evolutionary lineage within the radiation of the genus Nocardioides. The cell wall peptidoglycan of strain MSL-11T contained ll-diaminopimelic acid, indicating wall chemotype I. The predominant menaquinone was MK-8(H4). Strain MSL-11T had a cellular fatty acid profile containing straight-chain, branched, unsaturated, and 10-methyl fatty acids, with iso-C16:0 as a major fatty acid component detected. The DNA G + C content of the strain was 71.8 mol%. Comparative 16S rRNA gene sequencing revealed that the strains constituted a distinct subclade within the genus Nocardioides, displaying a 16S rRNA gene sequence similarity of about 95.68% with Nocardioides jensenii DSM 20641T. On the basis of both phenotypic and phylogenetic evidence, the strain is separated from previously described Nocardioides species and should be assigned to represent a novel species of the genus Nocardioides, for which the name Nocardioides dilutes sp. nov. is proposed. The type strain is strain MSL-11T (= KCTC 19288T = DSM 19318T).
