title: [Fusion of protoplasts of inactive variants of 2 producers of actinomycin C and the biosynthesis of an antibiotic of non- actinomycin nature].
abstract: Fusion of protoplasts of double auxotrophic mutants of spontaneous inactive variants of two cultures producing actinomycin C, i.e. Streptomyces chrysomalus 305 and Streptomyces sp. 26-115 induced by PEG-600 yielded a number of stable recombinants. One of the recombinants requiring proline for its growth was designated as recPro. Unlike its parent strains, it synthesized an antibiotic substance active against gram-positive bacteria and Saccharomyces cerevisiae. The nature of the substance is under investigation.
