VARIABILITY OF STRAINS OF BASIDIOMYCETES IRPEX LACTEUS TO SYNTHESIS OF SPECIFIC MILK-CLOTTING PROTEINASES
Abstract
The ability to synthesize of milk-clotting (rennet) proteinase in 8 strainsbasidiomycetesI.lacteus was studied. It is found that the investigated strains ofI.lacteus differ in enzyme activity of the culture liquid. Maximum milk-clotting activity ofstrainsI.lacteus 2425, 2426 and 2427 was observed in the exponential growth phase on the 15th day of cultivation on glucose-peptone medium. These strains ofI.lacteus are the most perspective producers of the milk-clotting enzymes for further research and practical application. Strains ofI.lacteus 2421, 2422, 2423, 2424 and 2428 showed lower values of enzymatic activity and require additional research on the selection of the optimal culture conditions.
