Abstract

Strain SH-6 was isolated from the sediment of Lake Shangmatala, a saline lake in Inner Mongolia (China). Cells were pleomorphic. The organism was neutrophilic and required at least 2.5 M (15 %) NaCl, but not MgCl, for growth; optimal growth occurred at 4.3 M (25 %) NaCl. The G+C content of its DNA was 63.1 mol%. 16S rRNA gene sequence analysis revealed that strain SH-6 is a member of the family , but there was a low level of similarity with other members of this family. Highest sequence similarity (94.6 %) was obtained with the 16S rRNA genes of the type strains of and . Polar lipid analyses revealed that strain SH-6 contains phosphatidylglycerol and phosphatidylglyceromethylphosphate, derived from both CC and CC glycerol diethers together with the glycolipid S-DGD-1. On the basis of the data obtained, the new isolate could not be classified in any recognized genus. Strain SH-6 is thus considered to represent a novel species in a new genus within the family , order , for which the name gen. nov., sp. nov. is proposed. The type strain of is SH-6 (=CECT 7173=CGMCC 1.6379=JCM 14033).
