| Abstract: | A novel actinomycete strain, designated TRM 40137T, was isolated from a hypersaline habitat in Xinjiang Province, north-west China, and subjected to a polyphasic taxonomic
study. The strain was aerobic, Gram-positive and the optimum NaCl concentration for growth was 4–5% (w/v). Phylogenetic analysis
showed that strain TRM 40137T has a 16S rRNA gene sequence similarity of 95.02% with the described species Glycomyces
sambucus E71T and can be distinguished from all previously described representatives of the genus Glycomyces. The whole-cell sugar pattern consisted of xylose and galactose. The predominant menaquinone was MK-10(H2) and the major fatty acids were anteiso-C15:0 and anteiso-C17:0. The phospholipid pattern consists of phosphatidylglycerol,
diphosphatidylglycerol, three unknown aminophospholipids and two unknown phospholipids. The G+C content of the genomic DNA
was 68.8 mol%. A novel species Glycomyces halotolerans sp. nov. is proposed, with strain TRM 40137T (=CCTCC AA 2010013T = KCTC 19988T) as the type strain of G. halotolerans. |
