We perform research with bioelectrochemical systems with either a diverse undefined mixed culture, a defined mixed culture, or a pure culture of microbes in the anode and/or cathode chambers. Our tenet is to study the mechanisms of electron transfer from bacteria to the electrode or vice versa, to optimize the reactor conditions, to overcome current limiting factors, to generate new bioproducts, and to design practical reactor configurations. We have published papers on the upflow microbial fuel cell (UMFC) a reactor concept that may be used one day as a practical wastewater treatment system that can produce electrical power. However, it is now also become clear that the electric power output will be low, and therefore a more potential lucrative idea is to generate useful products in the cathode of microbial electrolysis cells (MECs) from organic wastes that are oxidized in the anode. In addition, we use these systems as biosensors because bacteria can generate a digital output directly. In this area, our lab is developing biocomputing with bioelectrochemical systems.
