Nocardioides terrigena sp. nov., isolated from soil.
A Gram-positive, rod- or coccoid-shaped bacterial strain, DS-17T, was isolated from a soil in Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain DS-17T grew optimally at around pH 8.0 and 30 degrees C in the presence of 0.5-1.0% (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-17T belonged to the genus Nocardioides. The chemotaxonomic properties of strain DS-17T 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, C17:1omega8c and C17:0 were the major fatty acids. The DNA G+C content was 71.5 mol%. Strain DS-17T exhibited 16S rRNA gene sequence similarity values of 94.5-96.9% to the type strains of recognized Nocardioides species. Strain DS-17T could be distinguished from recognized Nocardioides species by differences in phenotypic characteristics. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DS-17T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides terrigena sp. nov. is proposed. The type strain is DS-17T (=KCTC 19217T=JCM 14582T).
