An actinomycete strain, isolated from a Mata Atlântica soil sample, showing cellulolytic activity was subjected to polyphasic taxonomic characterization to determine its identity. Strain M7aT presented morphological and chemotaxonomic characteristics consistent with its assignment to the genus Streptomyces. Phylogenetic analysis of its 16S rDNA sequence revealed that the strain differed from described streptomycetes available in the public databases; the most closely related species was Streptomyces laceyi, with 98.4% nucleotide similarity. It also differed from other cellulolytic strains in its phenotypic characteristics. It is therefore proposed that strain M7aT, a cellulolytic strain with biotechnological potential, represents a novel species, named Streptomyces drozdowiczii sp. nov. The type strain is M7aT (=CBMAI 0498T=CIP 107837T=NRRL B-24297T).
从大西洋森林土壤样本中分离出的一株具有纤维素分解活性的放线菌菌株，对其进行了多相分类学表征以确定其身份。菌株M7aT呈现出的形态和化学分类学特征与其归属于链霉菌属一致。对其16S rDNA序列的系统发育分析表明，该菌株与公共数据库中已描述的链霉菌不同；最密切相关的物种是拉氏链霉菌，核苷酸相似性为98.4%。它在表型特征上也与其他纤维素分解菌株不同。因此，建议将具有生物技术潜力的纤维素分解菌株M7aT代表一个新物种，命名为德罗兹多维奇链霉菌新种。模式菌株为M7aT（=CBMAI 0498T=CIP 107837T=NRRL B-24297T）。
