LACCASES AND MANGANESE PEROXIDASES OF PLEUROTUS OSTREATUS GROWN IN SOLID-STATE FERMENTATION

Ligninolytic system of white-rot fungi is directly involved in the degradation of various xenobiotic compounds and dyes. This system could show enzymes such as laccases, manganese peroxidases (MnP), veratryl alcohol oxidase (VAO) and versatile peroxidases (VP). In this work, laccase and manganese peroxidase activities of Pleurotus ostreatus grown in solid-state fermentation using polyurethane foam as inert support were evaluated. Maximal laccase activity was observed at the begin of stationary phase of growth and the manganese peroxidase showed the maximal activity at the end of fermentation.
