EXTRACELLULAR ENZYMES OF THE FUNGI PHANEROCHAETE-SANGUINEA AND CORIOLUS-VILLOSUS

The compositions of the extracellular enzyme complexes of the basidiom ycetes Coriolus villosus and Phanerochaete sanguinea were studied and their distinctions noted. Both fungi exhibit aryl-beta-glucosidase and xylanase activity; P. sanguinea has cellobiase activity as well. No o ther cellulase complex enzymes were found. The lignolytic complex of C . villosus contains laccase and ligninase; the P. sanguinea complex co ntains only Mn-peroxidase, The optimal medium Mn2+ concentration for M n-peroxidase formation was determined. A stimulating role of lignin on Mn-peroxidase synthesis was found.
