Sofia University, Biological Faculty, Department of
General and Industrial Microbiology,
8 Dragan Tzankov st., 1164 Sofia, Bulgaria
Summary
Strain
Streptomyces sp. 3B produces high activity extracellular proteolytic complex, in which serine- and metalloproteases are identified.
The general and some other significant properties for the taxonomy of the
strain were studied by the methods of the International Streptomycetes Project.
The results of the investigation of Streptomyces sp. 3B and the comparative
references about Streptomyces species with similar taxonomic characteristics
identified it as Streptomyces albovinaceus. The antibiotic activity and
sensitivity was also tested. Strain 3B was resistant to the group of the
penicillin antibiotics.
