Abstract

|
A Gram-negative, rod-shaped, gliding, aerobic bacterium, designated 12157T, was isolated from the desert of Xinjiang, China and subjected to a polyphasic taxonomic study. The strain 12157T grew optimally at pH 7.0 and 30 °C. MK-7 was the predominant respiratory menaquinone. The DNA G+C content was 42.0 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences showed that the isolate was mostly related to the members of the genus Pedobacter, with similarities ranging from 90.0 % to 93.7 %. Phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analysis support the establishment of a novel species, Pedobacter xinjiangensis sp. nov., with strain 12157T (=CCTCC AB 208092T=NRRL B-51338 T) as the type strain.
