A novel actinomycete, designated strain OU-63T, was isolated from garden soil collected on the campus of Osmania University in Hyderabad, southern India. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Streptomyces. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Streptomyces, and was related most closely to Streptomyces chartreusis NBRC 12753T (98.6% similarity). However, the mean level of DNA-DNA relatedness between the two strains was only 25+/-1.73%. Based on DNA-DNA relatedness, morphological and phenotypic data, strain OU-63T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces osmaniensis sp. nov. is proposed. The type strain is OU-63T (=CCTCC AA209025T =PCM 2690T).
一株新型放线菌，命名为 OU-63T 菌株，从印度海德拉巴奥斯马尼亚大学（Osmania University）校园采集的花园土壤中分离得到。该菌株具有典型的链霉菌属的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，该菌株属于链霉菌属，与绛红链霉菌（Streptomyces chartreusis）NBRC 12753T 最为密切相关（相似度为 98.6%）。然而，两株菌之间的平均 DNA-DNA 同源性仅为 25+/-1.73%。基于 DNA-DNA 同源性、形态学和表型数据，菌株 OU-63T 可与系统发育上相关的模式菌株区分开来。因此，它被认为代表了链霉菌属的一个新种，建议将其命名为奥斯马尼亚链霉菌（Streptomyces osmaniensis）。其模式菌株为 OU-63T（=CCTCC AA209025T =PCM 2690T）。
