LIGNINOLYTIC ENZYMES OF BASIDIOMYCETES - LIGNIN PEROXIDASES FROM THE FUNGUS PLEUROTUS-OSTREATUS UZBI-ZAX-108 .1. OPTIMIZATION OF PRODUCTIONAND ISOLATION OF LIGNINASE

Lignocellulose agriculture wastes-i.e., depleted cotton seed marc, cot ton stems, ambary boon, rice husks, and birch sawdust-can be used as t he components of culture medium for submerged cultivation of basidiomy cetes. Lignin peroxidase production by Panus tigrinus, Pleurotus ostre atus, Fomes fomentarius, and Inonotus hispidus fungi has been studied. Pleurotus ostreatus producing active lignin peroxidase degrades both lignocellulose and lignin. The biodegradation of plant wastes by this fungus has been studied. Optimum conditions for production of the enzy me and isolation of ligninase preparations with high specific activity have been determined.
