摘要：

The present work reports the production of laccase, lignin peroxidase and manganese peroxidase by the little studied white-rot fungus Phlebia floridensis under a variety of nutritional and physicochemical conditions. Among the different media and supplements the highest yields of laccase, lignin peroxidase and manganese peroxidase were recorded in the presence of sugarcane bagasse, wheat straw and rice straw, respectively. Laccase and manganese peroxidase activities were best expressed at a pH of 4.5 while lignin peroxidase was optimally active at a lower pH. Laccase proved to be much more thermostable as compared to the other two enzymes.
