A Streptomyces strain isolated from a hyper-arid Atacama Desert soil was characterised using a polyphasic taxonomic approach. The strain, designated C2(T), had chemical and morphological properties typical of the genus Streptomyces. The isolate formed a branch in the Streptomyces 16S rRNA gene tree together with the type strain of Streptomyces chromofuscus and was also loosely related to Streptomyces fragilis NRRL 2424(T). DNA:DNA relatedness values between the isolate and its two phylogenetic neighbours showed that it formed a distinct genomic species. The strain was readily distinguished from these organisms using a combination of morphological and phenotypic data. Based on the genotypic and phenotypic results, isolate C2(T) represents a novel species in the genus Streptomyces, for which the name Streptomyces bullii sp. nov. is proposed. The type strain is C2(T) (=CGMCC 4.7019(T) = KACC 15426(T)).
从极度干旱的阿塔卡马沙漠土壤中分离到的一株链霉菌菌株，采用多相分类方法进行了特征描述。该菌株被命名为 C2(T)，其化学和形态特征均典型地属于链霉菌属。该分离株与链霉菌属的模式种绛红链霉菌和脆弱链霉菌 NRRL 2424(T)一起形成了一个分支，在链霉菌 16S rRNA 基因树中。DNA:DNA 同源性值表明，该分离株与其两个系统发育上的近缘种形成了一个独特的基因组种。该菌株可以通过形态学和表型数据的组合很容易地与这些生物区分开来。基于基因型和表型结果，分离株 C2(T)代表链霉菌属中的一个新种，建议将其命名为棒状链霉菌（Streptomyces bullii）sp. nov.。其模式菌株为 C2(T)（=CGMCC 4.7019(T) = KACC 15426(T)）。
