Abstract

A Gram-stain-positive, rod-shaped, non-spore-forming bacterium, designated as x-2, was isolated from lakeside soil of Sayram in the Xinjiang Uygur Autonomous Region, PR China. On the basis of 16S rRNA gene sequences, strain x-2 belongs to the genus in the family , being most closely related to Gsoil 346 (97.36 % 16S rRNA gene sequence similarity). Strain x-2 was characterized chemotaxonomically and found to have -diaminopimelic acid in the cell-wall peptidoglycan, phosphatidylglycerol, diphosphatidylglycerol, glycolipids and another three unknown phospholipids as the major polar lipids, MK-8(H) as the predominant menaquinone and Cω9, iso-C, Cω8 and C as the major fatty acids. The genomic DNA GC content of the novel strain was 71.1 mol%. The level of DNA–DNA relatedness between strain x-2 and KCTC 19470 (=Gsoil 346) was 29.8 %. These chemotaxonomic characters support the position of strain x-2 within the genus . The results of physiological and biochemical tests, as well as phylogenetic analysis, suggest that strain x-2 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is x-2 (=KCTC 39845=CCTCCAB 2016255).
