A Gram-positive strain designated as MSL-14T isolated from a soil sample collected from Bigeum Island, Korea, was subjected to polyphasic taxonomy. The isolate was strictly aerobic. Cells were short rods and motile. Optimum growth temperature and pH was 28°C and 7.0, respectively. It was characterized chemotaxonomically as having a cell-wall peptidoglycan type based on LL-2,6-diaminopimelic acid and MK-8(H4) as the predominant menaquinone. The major fatty acids were iso-C16:0, C17:1 omega8c, and C18:1 omega9c. The G+C content was 67.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain MSL-14T is affiliated to the genus Nocardioides and formed a distinct lineage within the genus. MSL-14T showed highest sequence similarity to Nocardioides aestuarii JCM 12125T, having a similarity of 96.5%. Based on the 16S rRNA gene sequence divergence and phenotypic characteristics, it is proposed that strain MSL-14T should be classified as representing a novel member of the genus Nocardioides, for which we propose the name Nocardioides tritolerans sp. nov. The type strain is strain MSL-14T (=KCTC 19289T= DSM 19320T).
