An actinomycete, strain 4776(T), was isolated from soil collected from Emei Mountain in Sichuan Province, China. The taxonomic status of this strain was established using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of streptomycetes. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that the novel isolate belongs to the genus Streptomyces and consistently falls into a clade together with Streptomyces prasinopilosus DSM 40098(T), Streptomyces prasinus JCM 4603(T), Streptomyces bambergiensis DSM 40590(T), Streptomyces hirsutus DSM 40095(T) and Streptomyces cyanoalbus DSM 40198(T). However, DNA-DNA relatedness and phenotypic data distinguished strain 4776(T) from these phylogenetically related type strains. It is therefore concluded that strain 4776(T) (=CGMCC 4.3504(T)=DSM 41884(T)) represents a novel species of the genus Streptomyces, for which the name Streptomyces emeienseis sp. nov. is proposed.
从中国四川省峨眉山采集的土壤中分离出一株放线菌，菌株4776(T)。采用多相分类法确定了该菌株的分类地位。发现该菌株具有链霉菌典型的形态和化学分类特征。基于几乎完整的16S rRNA基因序列的系统发育分析表明，该新分离菌株属于链霉菌属，并且始终与绿色柔毛链霉菌DSM 40098(T)、绿色链霉菌JCM 4603(T)、班贝格链霉菌DSM 40590(T)、多毛链霉菌DSM 40095(T)和蓝白链霉菌DSM 40198(T)一起归入一个进化枝。然而，DNA-DNA杂交和表型数据将菌株4776(T)与这些系统发育相关的模式菌株区分开来。因此得出结论，菌株4776(T)(=CGMCC 4.3504(T)=DSM 41884(T))代表链霉菌属的一个新物种，为此提出新名称峨眉山链霉菌（Streptomyces emeienseis sp. nov.）。
