Abstract:
Streptomycetes are attractive microorganisms because of their high secretion capacity and for the production of secondary metabolites. We report the improvement of a PCR-based method for screening of solid media-grown Streptomyces transformants. By resuspending mycelium into 2.5-10% dimethyl sulfoxide (DMSO), extensive manipulation prior to PCR could be avoided, thus significantly reducing screening time. Results proved to be both reliable and specific.
