ABSTRACT
A novel bacterium, XHU 5135T, belonging to the genus Aidingimonas, 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 5-25â% (optimum, 10-13â%), 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 C19ââ0 cyclo ω8c and C16ââ0. The G+C content of the genomic DNA was 58.1âmol%. The affiliation of strain XHU 5135T with the genus Aidingimonas was confirmed by 16S rRNA gene sequence comparisons. The closest type strain was Aidingimonas halophile YIM 90637T, which showed a 16S rRNA gene sequence similarity of 97.5â%. The ANI value between XHU 5135T and the closest type strain was 80.01â%. The estimated digital DNA-DNA hybridization estimate value between strain XHU 5135T and the closest type strain was 22.80â%. Phenotypically, the characteristics of XHU 5135T were shown to differ from the most closely related species, A. halophila. On the basis of the data from this polyphasic study, strain XHU 5135T represents a novel species of the genus Aidingimonas, for which the name Aidingimonas lacisalsi sp. nov. is proposed. The type strain is strain XHU 5135T (=CCTCC AB 2016344T=KCTC 42945T=DSM 104700T).
