sp. nov., an actinomycete isolated from a hypersaline habitat Free

Abstract

A novel actinomycete strain, designated XHU 5089, was isolated from a hypersaline habitat in China. The strain was aerobic, Gram-stain-positive and the optimum NaCl concentration for growth was 1–3 % (w/v). Phylogenetic analysis based on the almost-complete 16S rRNA gene sequence of strain XHU 5089 showed that the organism was related most closely to TRM 49136 (97.7 % similarity). However, it had a relatively low mean DNA–DNA relatedness value with TRM 49136 (18.9±5.8 %). The whole-cell sugar pattern consisted of glucose and galactose. The predominant menaquinones were MK-10(H) and MK-9(H). The major fatty acids were anteiso-C, iso-C, iso-C and anteiso-C. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two unidentified glycolipids and two unknown phospholipids. The G+C content of the genomic DNA was 68.6 mol%. A novel species, sp. nov., is proposed, with XHU 5089 (=CCTCC AA 2015034=KCTC 39688) as the type strain.
