Glycomyces xinjiangensis sp. nov., a novel actinomycete isolated from a hypersaline habitat

Abstract

A novel actinomycete strain, designated XHU 5301T, was isolated from a hypersaline habitat, China. The strain was aerobic, Gram-stain positive and the optimum NaCl concentration for growth was 7–9% (w/v). Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of strain XHU 5301T showed that the organism was most closely related to Glycomyces halotolerans TRM 40137T (96.0%). The whole-cell sugar pattern consisted of glucose and galactose. The predominant menaquinone was MK-10(H4), MK-10(H2), and MK-9(H4). The major fatty acids were anteiso-C15: 0, iso-C15: 0, iso-C16: 0, and methyl-C19: 0. The polar lipids consist of diphosphatidylglycerol, phosphatidylglycerol, and one unknown phospholipid. The G+C content of the genomic DNA was 72.5 mol %. The novel species Glycomyces xinjiangensis sp. nov. was proposed, with strain XHU 5301T (=CCTCC AA 2016043T =KCTC 39689T) as the type strain of Glycomyces xinjiangensis.
