A Gram-negative, non-motile, rod-shaped bacterium, designated strain AKS 1T, was isolated from a desert soil sample collected from Akesu, XinJiang Province, China. A taxonomic study, including phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics, was performed on the novel isolate. The predominant menaquinone of strain AKS 1T was MK-7. The major fatty acids included i-C(15 : 0), ai-C(17 : 1) B/i-C(17 : 1) I and i-C(17 : 0) 3-OH. The G+C content of the DNA was 51.4 mol%. Based on the results of phenotypic and genotypic characteristics, strain AKS 1T should be assigned as representing a novel species of the genus Pontibacter, for which the name Pontibacter akesuensis is proposed. The type strain is AKS 1T (=KCTC 12758T=CCTCC AB 206086T).
