Abstract

A Gram-positive, non-motile actinobacterium, designated strain YIM 70177, was isolated from a saline soil sample from Qinghai Province, north-west China. Phylogenetic analysis of this organism based on 16S rRNA gene sequences revealed 98·3 % similarity to DSM 10177. Chemotaxonomic data determined for the isolate, such as the peptidoglycan type A4, variation -lys–-Asp, supported the placement of strain YIM 70177 within the genus . Galactose was detected as cell wall sugar. Phospholipids identified were phosphatidylinositol, phosphatidylglycerol and diphosphatidylglycerol, and the predominant menaquinones were MK-9(H) and MK-9(H). The major fatty acids were ai-C, C, ai-C and i-C. The DNA G+C content was 72·8 mol%. The low level of DNA–DNA relatedness (27·4 %) to DSM 10177 in combination with differentiating chemotaxonomic and physiological data demonstrated that the isolate YIM 70177 should be classified as representing a novel species of the genus . The name sp. nov. is proposed, with strain YIM 70177 (=DSM 16376=KCTC 19046) as the type strain.
