Abstract

Three strains of Gram-negative, aerobic, neutrophilic and halophilic bacteria were isolated from samples of a salt lake on the Qinghai–Tibet Plateau and a subterranean saline well in the Si-Chuan Basin of China. These isolates, designated AJ275, AJ282 and ZG16, were investigated using a polyphasic approach. Based on 16S rRNA gene sequence analysis, the isolates could be affiliated to the genus . Genomic DNA G+C contents were 65.9 mol% for AJ275, 56.7 mol% for AJ282 and 57.6 mol% for ZG16. The results of DNA–DNA hybridizations, fatty acid analysis and physiological and biochemical tests allowed the isolates to be differentiated genotypically and phenotypically from closely related species. It is proposed that strains AJ275 (=CGMCC 1.6493=JCM 14606=LMG 23976), AJ282 (=CGMCC 1.6494=JCM 14607=LMG 23978) and ZG16 (=CGMCC 1.6495=JCM 14608=LMG 23977) represent the type strains of three novel species in the genus : sp. nov., sp. nov. and sp. nov., respectively.
