Streptomyces drozdowiczii sp nov., a novel cellulolytic streptomycete from soil in Brazil

An actinomycete strain, isolated from a Mata Atlantica soil sample, showing cellulolytic activity was subjected to polyphasic taxonomic characterization to determine its identity. Strain M7a(T) 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 M7a(T), a cellulolytic strain with biotechnological potential, represents a novel species, named Streptomyces drozdowiczii sp. nov. The type strain is M7a(T) (=CBMAI 0498(T)=CIP 107837(T)= NRRL B-24297(T)).
