ABSTRACT
An aerobic bacterial strain, designated XJ-2T, was isolated from a soil sample collected from Gurbantunggut Sandy Desert in PR China. Cells of strain XJ-2T were Gram-stain-negative, non-motile, rod-shaped and non-spore-forming. The new isolate grew well at 10-37 °C (optimum, 28-30 °C), pH 6.0-11.0 (pH 7.0) and 0-1â% (w/v) NaCl (0â%). The 16S rRNA gene sequence of strain XJ-2T showed the highest similarity to that of Chitinophaga rhizosphaerae T16R-86T (99.0â%), followed by Chitinophaga barathri YLT18T (97.0â%), Chitinophagahumicola Ktm-2T (96.7â%) and Chitinophaga niabensis JS13-10T (96.4â%). The major menaquinone of strain XJ-2T was menaquinone 7 and the predominant fatty acids (>5â%) were iso-C15ââ0, C16ââ1ω5c and iso-C17ââ0 3-OH. The polar lipids consisted of phosphatidylethanolamine, an unidentified glycolipid, three unidentified aminolipids and five unidentified lipids. The genome size was 6.33 Mb, comprising 5268 predicted genes with a G+C content of 41.5âmol%. The DNA G+C content was 50.5 mol% based on total genome calculations. The average nucleotide identity and the digital DNA-DNA hybridization values between strain XJ-2T and strain T16R-86T were 79.6 and 22.3â%, respectively. DNA-DNA relatedness between strain XJ-2T and strain YLT18T was 17.0â%. Based on the physiological, biochemical and chemotaxonomic characteristics, strain XJ-2T represents a novel species of the genus Chitinophaga, for which the name Chitinophagadeserti sp. nov. is proposed. The type strain is XJ-2T (KCTC 62443T=CCTCC AB 2018019T).
