A novel actinobacterial strain, designated 13K301^T, was isolated from a soil sample collected from the Karakum Desert, Turkmenistan. The taxonomic position of strain 13K301^T was revealed by using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain 13K301^T belongs to the genus Streptomyces and had highest sequence similarity to ‘Streptomyces qaidamensis’ S10^T (99.2 %), Streptomyces flavovariabilis NRRL B-16367^T (98.9 %) and Streptomyces phaeoluteigriseus DSM 41896^T (98.8 %), but the strain formed a distinct clade in the phylogenetic tree. The DNA–DNA relatedness and average nucleotide identity values as well as evolutionary distances based on multilocus (atpD, gyrB, recA, rpoB and trpB) sequences between strain 13K301^T and closely related type strains were significantly lower than the recommended threshold values. The cell wall contained ll …
