Strain SR-1T, a Gram-positive, strictly-aerobic, short-rod shaped, non-motile bacterium, was isolated from a mountain soil collected in Seoul Women’s University in South Korea. Growth occurred between 15 and 37?°C (optimum, 30?°C), at pH 6.0-.0 (optimum, pH 7.0) and with 0-?% NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SR-1T belongs to the genus Nocardioides and is closely related to Nocardioides simplex KCTC 9106T (96.8?%), Nocardioides caeni MN8T (96.7?%), Nocardioides aromaticivorans H-1T (96.6?%), and Nocardioides kongijuensis A2-4T (96.6?%). Chemotaxonomic data revealed that strain SR-1T possesses MK-8(H4) as predominant menaquinone, ll-2,6-diaminopimelic acid as the diagnostic diamino acid, phosphatidylglycerol and diphosphatidylglycerol as predominant polar lipids and iso-C16:0, 10-methyl-C18:0, and C18:1 ω9c are major fatty acids. The DNA G+C content of the strain SR-1T was 72.4?mol%. Based on polyphasic evidence, strain SR-1T (=?KEMC 9004-134T?=?JCM 19684T) should be classified as the type strain of a novel Nocardioides species, for which the name Nocardioides soli sp. nov. is proposed.
