A novel Gram-positive, rod-shaped actinobacterium, designated strain YIM 90718, was isolated from a saline soil in Xinjiang province, north-west China, and subjected to polyphasic taxonomy. The peptidoglycan type was A1 and the cell-wall sugars contained galactose. Phospholipids were phosphatidylglycerol and diphosphatidylglycerol. The predominant menaquinone was MK-8(H). The major fatty acids were anteiso-C, anteiso-C and iso-C. All of these chemotaxonomic data assigned the new isolate YIM 90718 consistently to the genus . Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YIM 90718 formed a distinct phyletic lineage in the genus and showed the highest sequence similarity (96.2 %) to SST-8 and low similarity (<95.5 %) to other species of the genus . On the based of the polyphasic evidence, a novel species, sp. nov., is proposed, with the type strain YIM 90718 (=DSM 18261 =KCTC 19173 =CCTCC AB 206112).
