Scaling up the process of deep cultivation of the fungus Irpex lacteus (Fr.) Fr., a producer of cellulolytic enzymes

When scaling up the process of deep cultivation of the fungus Irpex lacteus (Fr.) Fr., a producer of exoenzymes of the cellulase complex, on a nutrient medium containing corn processing waste, the reproducibility of the results obtained in small volumes of the nutrient medium was established only at the initial stages of cultivation. The high enzymatic activity of the cellulase producer strain was observed from the 3^rd to the 10^th day of cultivation. A decrease in the enzymatic activity of the culture fluid was observed on the 15^th day of cultivation.
