[Biosynthesis of hydrolytic enzymes during cocultivation of macro- and micromycetes]. / Biosintez gidroliticheskikh fermentov pri sovmestnom kul'tivirovanii makro- i mikromitsetov.

Effects of co-cultivation of higher Basidiomycetes and Phycomycetes on the biosynthesis of cellulases, amylases, and proteases was studied. Four optimal pairs of fungal cultures were selected. Of these, three pairs belonged to higher fungi, and one pair was constituted by fungi of distinct ecological groups, a macromycete and a micromycete. The activities of amylase and protease were 1.5 to 2 times higher, and the activity of cellulase was lower during the growth of higher fungi associations. The mixed association of the macromycete Schizophyllum commune and the micromycete Mucor sp. was the most active producer of hydrolytic enzymes. During the growth of this mixed association, a fourfold and 1.5-fold increases were observed in the activity of endoglucanase and protease, respectively, paralleled by stimulation of amylase formation.
