Abstract
Microbial fuel cells (MFC) are bio-electrochemical devices that produce electricity by employing electroactive bacteria (EAB) as environmental monitoring assets. In this study, we developed a single chamber closed-circuit 3D-printed MFC for nitrate detection in water. The MFCs were matured by wastewater and synthetic wastewater, resulting in a maximum voltage output of 295 mV. The result of laboratory tests showed high sensitivity of carbon cloth MFC biosensor towards detection of nitrate with a minimum detection of 0.625 mg/L (lower concentrations will be tested prior to the conference). Moreover, real environmental water samples were tested by the MFC and showed promising results. Our future work will increase the sensitivity of the MFC by optimising the anode electrode material and external resistance.
