Abstract

A novel strain, designated 311-10T, isolated from soil of Xinjiang, China, was characterized by using a polyphasic taxonomic approach. The isolate was Gram-negative, aerobic, rod-shaped, non-motile, oxidase-negative and catalase-positive. The predominant menaquinone of strain 311-10T was MK-7 and the genomic DNA G+C content was 47.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate formed a cluster with the genera Pontibacter and [Effluviibacter] in the phylum ‘Bacteroidetes’, with sequence similarities of 93.9–95.6 %. Phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analyses support the reclassification of [Effluviibacter] roseus as Pontibacter roseus comb. nov. (type strain, SRC-1T=MTCC 7260T=DSM 17521T) and the establishment of a novel species, Pontibacter xinjiangensis sp. nov., with strain 311-10T (=CCTCC AB 207200T=NRRL B-51335T) as the type strain.
