During an investigation of microbial diversity in medicinal herbs, a novel actinomycete, strain NEAU-QHHV11T was isolated from the rhizosphere of Peucedanum praeruptorum Dunn collected from Xianglu Mountain in Heilongjiang Province, northeast China and characterized using a polyphasic approach. The organism was found to have typical characteristics of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequence also indicated that strain NEAU-QHHV11T belongs to the genus Streptomyces and was most closely related to Streptomyces graminilatus NBRC 108882T (98.7 % sequence similarity) and Streptomyces turgidiscabies NBRC 16080T (98.7 % sequence similarity). The results of DNA–DNA hybridization and some phenotypic characteristics indicated that strain NEAU-QHHV11T could be distinguished from its close phylogenetic relatives. Thus, strain NEAU-QHHV11T represents a novel species of the genus Streptomyces, for which the name Streptomyces castaneus sp. nov. is proposed. The type strain is NEAU-QHHV11T (=CGMCC 4.7235T = DSM 100520T).
