sp. nov., isolated from salt lake on the Tibetan plateau of China.

One bacterial strain, designated as C22-A2, was isolated from Lake LungmuCo in Tibet. Cells of strain C22-A2 were long rod-shaped, Gram-stain-negative, non-spore-forming, with positive catalase and oxidase activity. Optimal growth occurred at 20-25 °C, pH 8.0 and with 3.0-7.0% (w/v) NaCl. Phylogenetic analysis of 16S rRNA gene and whole genome sequences revealed that strain C22-A2 belonged to the genus , showing the highest 16S rRNA gene similarity to DSM 10037 (97.6%). The average nucleotide identity values between strain C22-A2 and the type strains of related species in the genus were less than 74.4% and the digital DNA-DNA hybridization values were less than 20.2%, both below the species delineation thresholds of 95 and 70% respectively. The genome analysis revealed that strain C22-A2 harboured genes responsible for osmotic and oxidative stress, enabling it to adapt to its surrounding environment. In terms of biochemical and physiological characteristics, strain C22-A2 shared similar characteristics with the genus including the predominant cellular fatty acid anteiso-C, the major respiratory quinone MK-7, as well as the polar lipids phosphatidylglycerol and diphosphatidylglycerol. Based on the comprehensive analysis of phylogenetic, phylogenomic, morphological, physiological and biochemical characteristics, strain C22-A2 is proposed to represent a novel species of the genus , named as sp. nov. (=CGMCC 1.19202=KCTC 43426).
