Fungi produce various types of extracellular enzymes, including the copper-containing oxidative enzyme laccase. This enzyme uses gaseous oxygen (O₂) as an electron acceptor to catalyze oxidation of phenolic compounds, and therefore it can act as a cathode biocatalyst in a microbial fuel cell (MFC). In this study, a new model of the air-cathode microbial fuel cell (AC-MFC) was constructed. For its...
Lignin-modifying enzymes have long been used in palm oil mill effluent (POME) treatment to remove the dark brown colour resulting from phenolic contamination. This study investigated a cost-effective industrial application method for optimizing phenol removal from POME using the termite-associated yeast Galactomyces reessii obtained from the subterranean termite under laboratory conditions. The yeast...
