Abstract:A novel actinobacterial strain, designated TRM SA0054T, was isolated from the roots of Sophora alopecuroides grown in Alar, Xinjiang, north-west China, and characterised by a polyphasic taxonomic approach. Phylogenetic analysis showed that strain TRM SA0054T has 16S rRNA gene sequence similarity of 98.22% with Streptomyces barkulensis RC 1831T. Whole cell hydrolysates of strain TRM SA0054T were found to contain ll-diaminopimelic acid as the diagnostic diamino acid and ribose, glucose and xylose as the major whole cell sugars. The major fatty acids were identified as iso-C16:0, iso-C16:1 G, anteiso-C17:0, anteiso-C15:0, C16:0, anteiso-C17:1 ω9c. The main menaquinones were determined to be MK-8 (H4), MK-9 (H6) and MK-9 (H8). The polar lipids were identified as diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified lipid. The G?+?C content of the genomic DNA was determined to be 73.04%. Strain TRM SA0054T has a relatively low DNA–DNA relatedness value with Streptomyces barkulensis RC 1831T as determined by calculating the average nucleotide identity value (ANI?=?84.1%). Based on the phenotypic, chemotaxonomic and phylogenetic data, it is concluded that strain TRM SA0054T should be designated as a novel species of the genus Streptomyces, for which the name Streptomyces carminius sp. nov. is proposed, with type strain TRM SA0054T (=?CCTCC AA 2016041T?=?KCTC39903T).
