Abstract

A novel bacterium, XHU 5135, belonging to the genus , was isolated from a salt lake sample collected in Xinjiang Province, north-west PR China. The isolate was Gram-stain-negative, rod-shaped and non-motile. The strain was catalase-positive and oxidase-negative. Growth occurred at NaCl concentrations of 5–25 % (optimum, 10–13 %), at 13–41 °C (35–37 °C) and at pH 6.0–10.0 (pH 7.0–8.0). The predominant ubiquinone was Q-9. The major fatty acids were C cyclo 8 and C . The G+C content of the genomic DNA was 58.1 mol%. The affiliation of strain XHU 5135 with the genus was confirmed by 16S rRNA gene sequence comparisons. The closest type strain was YIM 90637, which showed a 16S rRNA gene sequence similarity of 97.5 %. The ANI value between XHU 5135 and the closest type strain was 80.01 %. The estimated digital DNA–DNA hybridization estimate value between strain XHU 5135 and the closest type strain was 22.80 %. Phenotypically, the characteristics of XHU 5135 were shown to differ from the most closely related species, . On the basis of the data from this polyphasic study, strain XHU 5135 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is strain XHU 5135 (=CCTCC AB 2016344=KCTC 42945=DSM 104700).
