ABSTRACT
Two novel strains of actinobacteria, ZYC-3T and BH-SS-21T, were isolated from Hunan Province, PR China. The fermentation broth of BH-SS-21T inhibited the rapid spread of ginger blast, unlike that of ZYC-3T. The taxonomic characteristics of ZYC-3T and BH-SS-21T were defined using a polyphasic approach. The analysis of the full-length 16S rRNA gene sequence revealed that ZYC-3T and BH-SS-21T represented members of the genus Streptomyces. ZYC-3T had less than 98.7% sequence similarities to all species of the genus Streptomyces, while BH-SS-21T exhibited 99.97, 98.95, 98.83, 98.82, 98.75 and less than 98.7% sequence similarities to 'Streptomyces dioscori' A217, Streptomyces ederensis JCM 4958T, Streptomyces glomeroaurantiacus NBRC 15418T, Streptomyces aurantiacus NBRC 13017T, Streptomyces umbrinus JCM 4521T and other species with validly published names in the genus Streptomyces. However, the digital DNA-DNA relatedness and average nucleotide identity values between ZYC-3T, BH-SS-21T, and their closely related strains were significantly lower than the recommended threshold values. Also, phenotypic, chemotaxonomic and genetic features distinguished ZYC-3T and BH-SS-21T from their reference strains. On the basis of their genotypic and phenotypic characteristics, strains ZYC-3T and BH-SS-21T were classified as representing novel species of the genus Streptomyces under the names Streptomyces liliifuscus sp. nov. ZYC-3T (=CICC 25040T=JCM 34560T=MCCC 1K04978T) and Streptomyces liliiviolaceus sp. nov. BH-SS-21T (=MCCC 1K06236T=JCM 34767T), respectively.
