Abstract

Microbial fuel cells represent a promising technology for simultaneous wastewater treatment and renewable electricity production. However, the electricity recovery is still poor, typically <10% of what is theoretically possible and the extracellular electron transfer mechanisms are poorly understood. The use of co-cultures to improve substrate (glucose) turnover rate and hence electricity recovered was investigated initially. A co-culture of Shewanella oneidensis and Clostridium beijerinckii gave a maximum power density (Pmax) of 87 mWm-2 (67% COD reduction) compared to 60 mWm-2 for C.beijerinckii alone and 48 mWm-2 for S.oneidensis alone. Co-culturing Geobacter sulphurreducens, C. beijerinckii and Saccharomyces cerevisiae gave the highest ...
