Abstract

Abstract : A Gram-stain-negative, non-flagellated, rod-shaped bacterium, designated strain T22 T, was isolated from rhizosphere soil of Alhagi sparsifolia, collected from Xinjiang, China. Its major fatty acids (>5 %) were iso-C15 : 0, C16 : 1 ω5 c, iso-C17 : 0 -3OH, summed feature 1 (C13 : 0 3-OH/iso-C15 : 1 H) and summed feature 3 (C16 : 1 ω6 c /C16 : 1 ω7 c ). The predominant respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine, two aminolipids and four unidentified lipids. The DNA G+C content of the type strain was 53.4 mol%. According to phylogenetic analysis based on 16S rRNA gene sequences, strain T22 T was related most closely to Chitinophaga barathri YLT18 T (=CCTCC AB 2015054 T ) with similarity of 97.7 %. However, strain T22 T was clearly distinguished from Chitinophaga barathri YLT18 T using genome-to-genome distance and average nucleotide identity value calculation, as well as a range of physiological and biochemical characteristics comparisons. It is obvious from the genotypic and phenotypic data that strain T22 T represents a novel species of the genus Chitinophaga, for which the name Chitinophaga alhagiae sp. nov., is proposed. The type strain is T22 T (=ACCC 60125 T =KCTC 62518 T ).
