Scientists were not able, however, to develop a MFC that could produce electricity at a consistent rate . In the 1980s, British researcher H. Peter Bennetto succeeded in extracting electric power from MFCs by employing pure cultures of bacteria to catalyze the oxidation of organics and utilizing artificial electron mediators to facilitate electron transfer in the anode [10 – 13]. Meanwhile, Japanese researchers focused on using photoautotrophic bacteria as energy converters in a potentiostat-poised half cell or the anode of a MFC
