Abstract

Strain XH-48 was isolated from the sediment of Lake Xilinhot, a saline lake in Inner Mongolia (China). The organism is pleomorphic, neutrophilic and requires at least 2.5 M (15 %) NaCl, but not MgCl, for growth; it exhibits optimal growth at 3.4 M (20 %) NaCl. The G+C content of its DNA is 61 mol%. 16S rRNA gene sequence analysis revealed that strain XH-48 is a member of the family , but there were low levels of similarity with other members of this family. The highest sequence similarity values (94.5 and 93.3 %) were obtained with the 16S rRNA genes of and , respectively. Polar lipid analyses revealed that strain XH-48 contains phosphatidylglycerol and phosphatidylglyceromethylphosphate, derived from both CC and CC glycerol diethers, and two unidentified glycolipids. On the basis of the data obtained, the novel isolate cannot be classified within any recognized genus. Strain XH-48 should be placed within a novel genus and species within the family , order , for which the name gen. nov., sp. nov. is proposed. The type strain of is strain XH-48 (=DSM 17691=CGMCC 1.5338=JCM 13463=CECT 7116).
