The taxonomic status of this strain was established using a polyphasic approach. The morphological and chemotaxonomic characteristics of the organism are typical of the members of the genus Streptomyces . Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that strain Z4T belonged to the genus Streptomyces , branching off next to Streptomyces durhamensis ATCC 23194T (98.7 %), Streptomyces puniciscabiei KACC 20253T (98.7 %) and Streptomyces filipinensis ATCC 23905T (98.6 %). However, DNA–DNA hybridization studies and phenotypic differences between strain Z4T and closely related species of the genus Streptomyces suggested that strain Z4T represented a different genomic species. It is therefore proposed that Z4T ( = CGMCC 4.7035T = KCTC 29111T) represents the type strain of a novel species of the genus Streptomyces , for which the name Streptomyces yaanensis sp. nov. is proposed., language=, type=
