Abstract

A Gram-positive, non-motile, moderately halophilic, alkalitolerant actinobacterium, designated strain YIM 70179, was isolated from a saline soil sample collected from Xinjiang Province, north-west China, and was subjected to a polyphasic taxonomic study. The cell-wall peptidoglycan type of strain YIM 70179 was A4, -Lys–Gly–-Glu. Cells of the isolate contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and an unknown glycolipid, MK-8 as major menaquinone and anteiso-C, anteiso-C and iso-C as major fatty acids. The DNA G+C content was 68.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 70179 fell within the radiation of species of the genus . Levels of 16S rRNA gene sequence similarity between strain YIM 70179 and the type strains of recognized species were below 97 %, except to DSM 20541 (99.6 %), but these two strains exhibited a low level of DNA–DNA relatedness (18.4 %). Based on genetic and phenotypic evidence, it is proposed that strain YIM 70179 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YIM 70179 (=DSM 16378 =KCTC 19048).
