A cheap value-added product, the protein fraction of barley spent grains is proposed as a source of a potential and economical cultivation medium. We showed that medium composed of protein fraction extract allows the isolation of actinobacteria, especially Streptomyces, from soil samples, and enhances the sporulation. It was used for the screening and production of the biologically active substances from actinobacteria.
