A Gram-negative, non-motile and moderately halophilic rod-shaped bacterium, designated strain BH206T, was isolated from a saline lake of Xinjiang province in China. The isolate showed catalase-positive and oxidase-negative reactions and did not reduce nitrate. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate was most closely related to [Salegentibacter] catena HY1T with 95.8 % 16S rRNA gene sequence similarity, and formed a tight phyletic group with [Salegentibacter] catena HY1T with a bootstrap value of 99 % within the family Flavobacteriaceae. However, strain BH206T and [Salegentibacter] catena HY1T formed a phyletic lineage distinct from other Salegentibacter species. The 16S rRNA gene sequence similarities of strain BH206T with other related type species were lower than 94.6 %. On the basis of physiological and molecular properties, it is clear that [Salegentibacter] catena should be reclassified in the new genus Salinimicrobium as Salinimicrobium catena gen. nov., comb. nov. (type strain HY1T=CGMCC 1.6101T=JCM 14015T) and that strain BH206T represents a novel species within the genus Salinimicrobium, for which the name Salinimicrobium xinjiangense sp. nov. is proposed. The type strain of Salinimicrobium xinjiangense is BH206T (=KCTC 12883T=DSM 19287T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain BH206T is EF520007.
A transmission electron micrograph of cells of strain BH206T and a table showing the cellular fatty acid composition of strain BH206T and related type strains are available as supplementary material with the online version of this paper.
