Abstract

A novel extremely halophilic strain, AJ2, was isolated from Ayakekum salt lake located in the Altun Mountain National Nature Reserve in Xinjiang, China. This isolate was neutrophilic, motile and grew in a wide range of MgCl concentrations (0·005–1·0 M). The major polar lipids of the isolate were CC and CC derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and phosphatidylglycerol sulfate. A comprehensive 16S rRNA gene sequence analysis revealed that the isolate shared 96·6–97·7 % sequence identity with species. The isolate, however, could be genetically differentiated from these species by DNA–DNA hybridization analysis and on the basis of its physiological properties. On the basis of the polyphasic evidence, strain AJ2 (=AS 1.3731=JCM 12890) represents the type strain of a novel species, for which the name sp. nov. is proposed.
