Most of the known laccases are of fungal origin, in particular from the white rot fungi (Pleurotus Fungi). These fungi secrete lignolytic enzymes, which generate radical species that cause the complete biodegradation of lignin polymers. Oyster mushrooms are a good source of dietary fibre and other valuable nutrients. They also contain a number of biologically active compounds with therapeutic activities. Oyster mushrooms modulate the immune system, inhibit tumour growth and inflammation, have hypoglycaemic and antithrombotic activities, lower blood lipid concentrations, prevent high blood pressure and atherosclerosis, and have antimicrobial and other activities. The objectives of this study was to assess the ability of the obtained crude laccase in the enzymatic degradation of xenophytic compound 2,4-D. Laccase production from this fungal strain is reduced.
