Protoplasts of commercial strain No. 1 of Streptomyces roseolus producing lincomycin were prepared. Conditions for protoplast storage and regeneration were defined. The protoplasts of strain No. 1 mutants marked by the rifampicin and thiostrepton res

The influence of protoplasting and regeneration on the strains of the erythromycin-producing organism differing by their origin was studied with respect to changes in the antibiotic production property. 223 regenerates of the erythromycin-producing c

The spectrum of the mutations obtained with exposure of nonactivated spores of Pen. chrysogenum to N-nitrozo-N-methylbiuret (NMB) was studied and it was shown that the mutations associated with blocking of amino acid synthesis predominated. When acti

The mutagenic effect of nitrosocompounds is known to be dependent on pH. The effect of N-nitrozo-N-methylbiuret on the conidia of Penicillium chrysogenum was studied within the ranges of pH from 5.0 to 7.0, the role of the buffer and distilled water

The methods for preparation and regeneration of protoplasts were tested with respect to the strains of F. coccineum markedly differing in their capacity for antibiotic production, sporulation and the growth rate. It was found that the substrate used

The effect of UV light on activated conidia of Penicillium chrysogenum, strain 39 was studied. It was found that the spectrum of the auxotrophic mutations induced by UV light during replication of DNA changed with the dose of the mutagen and was spec
