Abstract

A Gram-negative, rod-shaped, non-motile, non-spore-forming bacterium, designated strain HR2, was isolated from a soil sample from the Taklimaken Desert in Xinjiang Province, China. Strain HR2 grew optimally at pH 7.0–8.0 and 30–37 °C in the presence of 0–1 % (w/v) NaCl. An analysis of 16S rRNA gene sequences revealed that strain HR2 fell within the radiation of the genus , the highest level of similarity being found with respect to IAM 13000 (97.5 %); the levels of sequence similarity with respect to other recognized species were <96.4 %. DNA–DNA hybridization showed that the genetic relatedness between strain HR2 and IAM 13000 was 53.2 %. The G+C content of the genomic DNA of strain HR2 was 55.2 mol%. The major fatty acids were 18 : 1, summed feature 3 and 16 : 0. The hydroxylated fatty acids 10 : 0 3-OH, 12 : 0 3-OH and 12 : 0 2-OH were also present. The data obtained in this polyphasic study indicated that this isolate represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HR2 (=KCTC 22129=CGMCC 1.6858).
