Degradation of poplar wood by Fomes sclerodermeus: Production of ligninolytic enzymes in sawdust of poplar and cedar

Fomes sclerodermeus is a white-rot fungus. Its production of laccase, manganese peroxidase and lignin peroxidase on sawdust-based media was evaluated. No lignin peroxidase activity was measured in any media tested. The higher production of laccase and manganese peroxidase were found on media contain...
