Methods for the production and analysis of cellulase and hemicellulase enzyme preparations of various compositions based on the Penicillium verruculosum carbohydrase complex and intended for the effective hydrolysis of different types of cellulose-containing materials (CCMs) have been developed. New recombinant strains of P. verruculosum producing(More)
Based on the fungus Penicillium verruculosum, we created strains with a complex of extracellular enzymes that contains both cellulolytic enzymes of the fungus and heterologous pectin lyase A from P. canescens and endo-1,4-a-polygalacturonase from Aspergillus niger. The endopolygalacturonase and pectin lyase activities of enzyme preparations obtained from(More)
The producer of fungal penicillopepsin, an aspartate protease, has been created by genetic engineering. The biochemical and physicochemical properties of the penicillopepsin enzyme preparation obtained from the culture liquid of the producer were studied. Properties of the new enzyme preparation and the commercially available aspergillopepsin were compared.(More)
Recombinant strains of Penicillium canescens producing homologous pectin lyase A and heterologous endo-1,5-α-arabinase A and endo-1,4–α-polygalacturonase, as well as enzymes of the host strain (α-L-arabinofuranosidases, xylanases, and others), were obtained by genetic engineering. The enzyme preparations (EPs) obtained from the cultural medium of(More)
Complex enzymatic preparations demonstrating activities homologous to pectinlyase A and heterologous to endo-1,4-β-glucanase from Penicilliumverruculosum and β-glycosidase from Aspergillusniger have been obtained on the basis of recombinant strains of the fungus Penicilliumcanescens. Two approaches were utilized: development of an enzymatic preparation on(More)
