Operation and characterization of a microbial fuel cell fed with pretreated cheese whey at different organic loads

► Electricity production from filter sterilized cheese whey at different organic loads. ► Electrochemical characterization of MFC through EIS measurements. ► Electrochemical characterization of anode and cathode through EIS measurements. ► Determination of cheese whey and glucose effect on the internal resistance of MFC. ► Effect of substrate exhaustion on the internal resistance of MFC.
