Streptomyces Drozdowiczii Sp. Nov., A Novel Cellulolytic Streptomycete From Soil In Brazil

An actinomycete strain, isolated from a Mata Atlântica soil sample, showing cellulolytic activity as 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). © 2004 IUMS.54413231328Altschul, S.F., Madden, T.L., Schaffer, A.A., Zhang, J., Zhang, Z., Miller, W., Lipman, D.J., Gapped BLAST and PSI-BLAST: A new generation of protein database search programs (1997) Nucleic Acids Res., 25, pp. 3389-3402Bull, A.T., Goodfellow, M., Slater, J.H., Biodiversity as a source of innovation in biotechnology (1992) Annu.
