sp. nov., isolated from rhizosphere soil of No Access

Abstract

A Gram-negative, aerobic, gliding motile, rod-shaped bacterium, designated XAAS-72, was isolated from the rhizosphere soil of sampled in the Xinjiang Uyghur Autonomous Region, PR China. Cells grew at 4–45 °C, pH 5.0–8.0 and 0–8% NaCl, with optimal growth at 20–30 °C, pH 6.0–7.0 and 1–2 % NaCl. Strain XAAS-72 is closely related to members of the genus , namely CCTCC AB 206081 (97.6%) and ACCC 19859 (97.2 %), and <94.6 % related to other currently described strains. The average nucleotide identity values between XAAS-72 and CCTCC AB 206081 and ACCC 19859 were 77.9 and 86.9 %, respectively; the corresponding digital DNA–DNA hybridization values were 21.7 and 31.8 %. Menaquinone-7 was the predominant respiratory menaquinone. The polar lipids consisted of phosphatidylethanolamine, two unidentified aminophospholipids, two unidentified glycolipids and five unidentified lipids. The major cellular fatty acids were summed feature 4 (containing iso-C I/anteiso-C B), summed feature 3 (containing C 7/C 6) and iso-C. The genome length of strain XAAS-72 was 5 054 860 bp with a genomic DNA G+C content of 54.5 mol%. The phenotypic and genotypic data suggest that strain XAAS-72 represents a novel species of the genus , for which the name sp. nov. is proposed. The strain is XAAS-72 (CGMCC 16594=KCTC 72095).
