A strain of Streptosporangium with an unusual phospholipid pattern was isolated from Yunnan Province, a region in China. The isolate, designated CY-7113T, was identified by morphological and physiological properties, cell chemistry, genomic DNA G+C content, DNA-DNA hybridization and phylogenetic analysis. Based on 16S rRNA gene sequencing, DNA-DNA hybridization, phenotypic characteristics and its unusual phospholipid pattern, it was concluded that strain CY-7113T belongs to a novel Streptosporangium species, for which the name Streptosporangium subroseum sp. nov. is proposed. Strain CY-7113T (= CCTCC 97008T = CRC 16302T) is the type strain.
