abstract= A Gram-stain-negative, non-motile, aerobic, rod-shaped bacterium, designated 15182T, was isolated from a saline lake in China. The novel strain 15182T was able to grow at 10–40 °C (optimum, 37 °C), pH 7.0–8.0 (optimum, 7.5) and with 0.5–4 % NaCl (optimum, 2–3 %, w/v). The phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 15182T was most closely related to the genus Rhodohalobacter by sharing the highest sequence similarity of 97.0 % with Rhodohalobacter halophilus JZ3C29T. Chemotaxonomic analysis showed that the sole respiratory quinone was menaquinone 7, the major fatty acids included C16 : 0 N alcohol and C16 : 1 ω11c. The major polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four uncharacterized glycolipids, one uncharacterized phospholipid and two uncharacterized lipids. The genomic DNA G+C content of the strain 15182T was 42.4 mol%. The average nucleotide identity value between 15182T and R. halophilus JZ3C29T was 75.4 %, and the in silico DNA–DNA hybridization value of the two strains was 19.1 %. On the basis of its phenotypic, chemotaxonomic, genotypic and genomic characteristics presented in this study, strain 15182T is suggested to represent a novel species in the genus Rhodohalobacter, for which the name Rhodohalobacter barkolensis sp. nov. is proposed. The type strain is 15182T (=KCTC 62172T=MCCC 1K03442T). An emended description of the genus Rhodohalobacter is also presented.,
