A novel actinomycete, designated strain NEAU-C3ᵀ, was isolated from volcanic sediment collected from Longwan, Jilin province, north China and characterized using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of the members of the genus Streptomyces. EzTaxon-e analysis of the 16S rRNA gene sequence indicated strain NEAU-C3ᵀto be most closely related to Streptomyces hygroscopicus subsp. ossamyceticus JCM 4965ᵀ(97.7 % sequence similarity) and Streptomyces torulosus JCM 4872ᵀ(97.7 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-C3ᵀbelongs within the genus Streptomyces and forms a separate subclade, an association that was supported by a bootstrap value of 72 % in the neighbour-joining tree and also recovered with the maximum-likelihood algorithm. The DNA–DNA hybridization values between strain NEAU-C3ᵀand the two most closely related type strains were low enough to justify the assignment of the strain to a novel species. On the basis of these phenotypic, phylogenetic and chemotaxonomic characteristics, it is concluded that strain NEAU-C3ᵀrepresents a novel species of the genus Streptomyces, for which the name Streptomyces vulcanius sp. nov. is proposed. The type strain is NEAU-C3ᵀ(=CGMCC 4.7177ᵀ=DSM 42139ᵀ).
