Abstract

A Gram-positive, aerobic actinomycete, designated strain YIM 45725, was isolated from a forest soil sample in Yunnan Province, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate was a member of the family and was related most closely to IM 7744 (99.4 % 16S rRNA gene sequence similarity). Chemotaxonomic data, including cell-wall components, menaquinones and polar lipids, supported the affiliation of strain YIM 45725 to the genus . The results of physiological and biochemical investigations and DNA–DNA hybridization experiments demonstrated that strain YIM 45725 differed from the single recognized species of the genus . Strain YIM 45725 is therefore considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YIM 45725 (=CCTCC AA 206004=DSM 18448).
