Abstract

A halophilic, Gram-negative bacterial strain, designated AJ261, which was isolated from a soil sample from a salt lake on the Qinghai–Tibet Plateau, was subjected to a polyphasic taxonomic study. The isolate grew optimally in the presence of 3–5 % NaCl and used various carbohydrates as sole carbon and energy sources. The genomic DNA G+C content was 63.0 mol%. The predominant fatty acids were C 7, C and C. A phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate had the highest sequence similarity with respect to type strains of (98.2 %), (98.1 %) and (97.2 %). The DNA–DNA relatedness of strain AJ261 with respect to NBRC 15536, CGMCC 1.2318 and DSM 5349 was 42, 25 and 26 %, respectively. Overall, the phenotypic, genotypic and phylogenetic results demonstrate that strain AJ261 represents a novel species within the genus , for which the name is proposed. The type strain is AJ261 (=CGMCC 1.6773 =JCM 14802).
