Abstract
Electrodes and configurations for electrochemical bioreactor systems that can use electrical energy as a source of reducing power in fermentation or enzymatic reactions and that can use electron mediators and a biocatalyst, such as cells or enzymes, to produce electricity are disclosed. Example electrodes in the system may comprise: (1) neutral red covalently bound to graphite felt (FIG.); (2) a carboxylated cellulose bound to the graphite fell, neutral red bound to the carboxylated cellulose, NADto the graphite fell, and an oxidoreductase (e.g., fumarate reductase) bound to the graphite fell; or (3) a metal ion electron mediator bound to graphite. Various biocatalysts, such as an oxidoreductase, cells ofcells ofand sewage sludge, are suitable for use in the electrochemical bioreactor system.
