White rot fungi produces various isoforms of extracellular enzymes including laccase, manganese peroxidase and lignin peroxidase that can degrade the pollutants and, thus, can be used to treat wastewater, including landfill leachate. In this research, the treatment of leachate by using white rot fungi, namely Trametes versicolor BCC 8725 and Flavodon flavus BCC 17421 was studied. Four types of leachate were collected in different time period and different source from Nonthaburi solid waste disposal site, Thailand. Leachate differs in terms of color, BOD, COD. The fungi were immobilized on...
