INGENIEUR can be used as feed for the anode respiring bacteria that subsequently releases the electrons from the oxidation process. The flow of electrons from anode to cathode generates electricity with circuit stabilisation that is achieved from proton (H + ) flow via the PEM (proton exchange membrane). In addition, the dissolved oxygen (DO) profile has also been found to have a clear positive correlation with the voltage output in the MFC system. To compensate for the high cost that arises from harvesting and post-proces
