A novel actinomycete, designated strain OU-40(T), was isolated from farm soil collected from the Hyderabad region of Andhra Pradesh, southern India. The strain was found to have morphological and chemotaxonomic characteristics typical of species of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain OU-40(T) belonged to the genus Streptomyces, and was related most closely to Streptomyces pactum NBRC 13433(T) (99.0 % sequence similarity), Streptomyces olivaceus NBRC 12805(T) (99.0 %) and Streptomyces parvulus NBRC 13193(T) (98.8 %). Strain OU-40(T) could be distinguished from the type strains of its closest phylogenetic relatives based on levels of DNA-DNA relatedness and comparison of morphological and phenotypic data. It is therefore concluded that strain OU-40(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces hyderabadensis sp. nov. is proposed. The type strain is OU-40(T) (=CCTCC AA 209024(T) =PCM 2692(T)).
一株新型放线菌，命名为 OU-40(T) 株，从印度安得拉邦海德拉巴地区采集的农田土壤中分离得到。该菌株具有典型的链霉菌属形态学和化学分类学特征。基于 16S rRNA 基因序列的系统发育分析表明，OU-40(T) 株属于链霉菌属，与链霉菌 pactum NBRC 13433(T)（99.0%序列相似性）、链霉菌 olivaceus NBRC 12805(T)（99.0%）和链霉菌 parvulus NBRC 13193(T)（98.8%）最为密切相关。OU-40(T) 株可根据 DNA-DNA 同源性水平和形态学及表型数据的比较，与亲缘关系最密切的模式菌株区分开来。因此，OU-40(T) 株代表链霉菌属的一个新种，建议将其命名为海德拉巴链霉菌（Streptomyces hyderabadensis sp. nov.）。其模式菌株为 OU-40(T)（=CCTCC AA 209024(T)=PCM 2692(T)）。
