The taxonomic position of a staurosporine-producing actinomycete isolated from a hay meadow soil was determined using a polyphasic approach. The organism had chemical and morphological characteristics consistent with its classification in the genus Streptomyces and formed a distinct branch between the Streptomyces lydicus and Streptomyces noursei clades in the 16S rRNA Streptomyces gene tree. DNA-DNA relatedness values between the isolate and its nearest phylogenetic neighbours, namely Streptomyces lydicus NBRC 13058T and Streptomyces chattanoogensis NBRC 12754T, were 53 % and 40 %, respectively. The isolate was also readily distinguished from the type strains of these species using a combination of morphological and other phenotypic properties. On the basis of these results, it is proposed that isolate BK179T (=KACC 20912T=NRRL B-24850T) be classified as the type strain of Streptomyces staurosporininus sp. nov.
从干草草坪土壤中分离出的产星形孢菌素放线菌的分类地位采用多相方法确定。该生物具有化学和形态特征与其在链霉菌属中的分类一致，并在 16S rRNA 链霉菌基因树中，形成了链霉菌利迪链霉菌和链霉菌诺斯雷亚种之间的明显分支。分离株与其最近的系统发育邻居，即链霉菌利迪氏菌 NBRC 13058T 和链霉菌查塔努加ensis NBRC 12754T 的 DNA-DNA 相关值分别为 53%和 40%。该分离株还可以通过形态和其他表型特性的组合，很容易与这些种的模式株区分开来。基于这些结果，建议将分离株 BK179T（=KACC 20912T=NRRL B-24850T）分类为新型星形孢菌素链霉菌的模式株。
