Kineococcus xinjiangensis sp. nov., isolated from desert sand

Abstract

A brown-orange-pigmented, non-spore-forming, coccus-shaped actinomycete, designated S2-20(T), 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 S2-20(T) 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 S2-20(T) represents a species that is separate from recognized Kineococcus species. Its major fatty acid was anteiso-C(15 : 0). The major menaquinone was MK-9(H(2)). Whole-cell hydrolysates of strain S2-20(T) 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 S2-20(T) 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 S2-20(T) (=CCTCC AB 207179(T) =KCTC 19474(T)).
