the development of MFC-based biosensors that act as early warning systems for the evaluation of the toxicity of water MFCs use electrogenic microorganisms capable of directly transducing chemical energy, contained within organic species ( fuel ) into electrical energy. These bacteria, capable of proliferating on the anode electrode, in fact, perform the function of catalysts of the fuel oxidation reaction, releasing the electrons produced to the electrode itself, integrating the detection and transduction of the signal together, without the aid of external transducers or power sources. The electrons flow into the cathode compartment where oxygen and the electron acceptor (TEA) for the cathodic reduction reaction. MFCs, therefore, guarantee the production of bioelectricity which can be correlated to the monitoring of environmental parameters, being able to correlate the change in output potential with the presence of toxic agents capable of altering microbial metabolism.
