A Gram-negative, coccoid to short rod-shaped, non-spore-forming, moderately halophilic bacterium, designated strain YIM 90738, was isolated from a salt lake in Xinjiang province, north-west China, and was subjected to a polyphasic taxonomic study. The strain was non-motile and grew at pH 6.0–8.0 (optimal growth at pH 7.0), 10–55 °C (optimal growth at 37 °C) and salinities of 1–15 % NaCl (w/v, optimal growth at 8 % NaCl). Ubiquinone 10 was detected as the major respiratory quinone. The cellular fatty acid profile had C 7 (80.4 % of the total) as the major component, similar to those of members of the genus . The nearest phylogenetic neighbour of strain YIM 90738 was the type strain of , as determined by 16S rRNA gene sequence analysis (97.5 % similarity). The level of DNA–DNA relatedness between DSM 17862 and strain YIM 90738 was 51.5 %. The G+C content of the genomic DNA of strain YIM 90738 was 60.3 mol%. On the basis of phenotypic and phylogenetic data and its genotypic distinctiveness, strain YIM 90738 (=CCTCC AB 206074 =KCTC 22163) is proposed as the type strain of a novel species of the genus , sp. nov.
