Dongia deserti sp. nov., Isolated from the Gurbantunggut Desert Soil

A Gram-stain-negative, aerobic, short rod-shaped strain, designated as SYSU D60009T, was isolated from a dry sandy soil sample collected from the Gurbantunggut Desert in Xinjiang, northwest China. Strain SYSU D60009T was observed to grow at 15–42 °C (optimum at 37 °C), pH 4.0–10.0 (optimum at 7.0), and with 0–0.5% (w/v) NaCl (optimum, 0%). The strain grew well on R2A agar, and colonies were smooth, white-pigmented, and circular with low convexity. The polar lipids consisted of phosphatidylethanolamine, aminolipid, aminophospholipid, and unknown lipids. The major cellular fatty acid (> 10%) was C16:0 and the predominant respiratory quinone was Q-10. Whole genome sequencing of strain SYSU D60009T revealed 6,132,710 bp with a DNA G + C content of 63.6%. The ANI and dDDH values of strains SYSU D60009T to Dongia mobilis CGMCC 1.7660 T were 72.8% and 19.0%, respectively. Based on the phenotypic, phylogenetic, and chemotaxonomic properties, strain SYSU D60009T represents a novel species of the genus Dongia, for which the name Dongia deserti sp. nov. is proposed, the type strain is SYSU D60009T (= CGMCC 1.16441 T = KCTC 52790 T).
