AbstractToday’s most pressing problems would greatly benefit from an integrated production method for food, water, and energy. Biological fuel cells can offer such a production method, but current designs cannot be scaled to meet global demand. The ability of five different fungal strains to secrete laccase was evaluated under optimized culture conditions using three inducers. A specialized electrode was developed to increase the loading of laccase on the cathode. Trametes versicolor was then immobilized at the modified cathode and shown to secrete electrochemically active laccase. This hybrid design combines the power density of an enzymatic catalyst with the robustness of a microbial catalyst by facilitating biological renewal of the enzymatic catalyst laccase.
