This presentation will give an overview and discuss a series of anode and cathode reactions based on direct electron transfer between the biological component (enzyme/organelle/whole cell) and various electrodes for possible applications in biofuel cells. Cathode reactions will include those based on direct electron transfer between enzymes able to reduce oxygen directly to water such as the high potential blue multicopper oxidases (laccase and bilirubin oxidase) and electrodes . Anode reactions will cover those based on direct electron transfer between both isolated redox enzymes (e.g., diaphorase, alcohol PQQ dehydrogenase, cellobiose dehydrogenase, hydrogenase [2,3]) and electrodes as well as direct electron transfer between bacteria and electrodes [4,5].
