Microbial Fuel Cell (MFC)
The production of electrical energy from bacterial energy by the use of Microbial Fuel Cell (MFC) has numerous future advantages. It would be a great way to generate energy out of bio waste omitting gas treatment and direct conversion of substrate energy to electricity. How MFC’s generates electrical energy? In a microbial fuel cell (MFC), bacteria do not directly transfer their electrons to their particular terminal electron acceptor rather these electrons facilitated by mediators are diverted towards an electrode, i.e. an anode. The electrons are then conducted over a resistance or power user towards a cathode and thus, bacterial energy is directly converted to electrical energy. To close the cycle, protons migrate through a proton exchange membrane. In actual, the bacteria in these cells transfer electrons generated during respiration, which then travel through the chosen circuit to a cathode, where they reduce oxygen to form water hence generating power-4.31 watt per square meter of electrode. MFCs has future applications in waste water arrangement, renewable biomass conversion, amd bio energy production from living plants in MFCs.
