Microbial Fuel Cell: An Efficient Method to Utilize Prokaryotic Potential to Engender Reliable Energy

Ankur B and Shipra S

A MFC (Microbial Fuel Cell), a microbial power module is a novel and exquisite advancement serving reasonable and green bio-vitality change innovation in the midst of microbial assimilation of regular acids and sugars. In commenced work twofold microbial operated energy chambers were constructed with diverged nature of microorganisms. In MFC-R1, E. coli (Escherichia coli) was utilized in anode slot while in MFC-R2, the sludge samples, anaerobically activated were exploited as anode and aerobically activated in cathode. The extreme yield of voltage was 150 mV in MFC-R1 after adding glucose and 400 mV in MFC-R2. In absence of appropriate air circulation in MFC-R1 voltage yield was diminished to 110 mV, while after proper aeration, the voltage yield has increased up-to 140 mV. In MFC-R2 voltage generation was reduced (250 mV) in deficiency of airing and increased up-to 400 mV after providing proper aeration. In MFC-R2, the higher voltage sustained for an extensive period (for 4 days) while in MFC-R1 voltage output declined after Day 1. This may be happened because in MFC-R2, additional substrates (the sludge samples rich in biomass/nutrients) were present and diverse sorts of microbes may be grown under wild conditions (belonging to different genus/species/strains) to utilize that substrate. Subsequently, the MFCs are being produced for both waste management besides bio-electricity generation and what's more, the thought would be fiscally functional and cooperative ecologically.
