摘要: A novel extremely halophilic strain, AJ2(T), was isolated from Ayakekum salt lake located in the Altun Mountain National Nature Reserve Xinjiang, China. This isolate neutrophilic, motile and grew a wide range of MgCl(2) concentrations (0.005-1.0 M). The major polar lipids were C(20)C(20) C(20)C(25) derivatives phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester sulfate. comprehensive 16S rRNA gene sequence analysis revealed that shared 96.6-97.7 % identity with Natrinema species. isolate, however, could be genetically differentiated these species by DNA-DNA hybridization on basis its physiological properties. On polyphasic evidence, strain AJ2(T) (= AS 1.3731(T) = JCM 12890(T)) represents type species, for which name altunense sp. nov. is proposed.
