A brown–orange-pigmented, non-spore-forming, coccus-shaped actinomycete, designated S2-20T, was isolated from desert sand from Xinjiang Province in China. The isolate stains Gram-positive, is motile and produces a brownish diffusible pigment. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2-20T was phylogenetically affiliated to the genus Kineococcus, and the sequence similarity to the type strains of Kineococcus species was less than 96 %, making it clear that strain S2-20T represents a species that is separate from recognized Kineococcus species. Its major fatty acid was anteiso-C15 : 0. The major menaquinone was MK-9(H2). Whole-cell hydrolysates of strain S2-20T contained meso-diaminopimelic acid, arabinose and galactose. The DNA G+C content was 77.8 mol%. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain S2-20T should be classified within a novel species of the genus Kineococcus, for which the name Kineococcus xinjiangensis sp. nov. is proposed. The type strain is S2-20T (=CCTCC AB 207179T =KCTC 19474T).
