The global demand for ecofriendly and more efficient electricity production has

paved the way for discovery of alternative fuels and power generation. Bioelectricity is

an alternative method for the conventional energy production methods like

hydroelectric production, wind energy, thermal energy and atomic energy resources.

Bioelectricity can be produced from by making use of any actively growing biological

system especially making use of microorganisms, the growth and adaptability of this

microbial system is of primary concern in producing bioelectricity. Interestingly our

natural environment gives a lot of energy resources. For the planet earth the primary

source energy is sunlight. Energy flow from the sun will be converted into various

stages of tropics of energy levels where in the interaction of biotic and abiotic

components make the energy flow in an ordinary way. The demand for energy needs

Energy needs in the world continue to increase at an unsustainable rate. These energy

needs are met by fossil fuels that are non-renewable in nature and in future. The major

energy resources are fossil fuels such as coal, natural gas and oil. The rapid

advancement in science and technology followed by a fast-paced exponential growth in

social and economic arenas, combined with the continuous use of fossil fuels has

resulted in major concern in bioenergy production. Due to climate change there is a

global demand for the reserves of oil and natural gas and this concerns the search for

alternative energy which is renewable, sustainable and pollution free. Bio-energy is a

replacement energy source for fossil fuels due to the above-mentioned criteria.

A potential solution to energy generation is offered by Biological fuel cell. The

energy stored as chemicals can be converted into volts in Microbial Fuel Cells (MFC).

The chemical energy is converted into electrical energy at the two electrode interface

by organisms which undergo combustion with the release of energy and biocatalysation

of organic substance by oxygen. In the microbial fuel cell system, in an electrochemical

process, the enzyme catalytic energy is converted to electrical energy . Over the traditional

methods of electricity production, the use of microbial fuel cell has many potential advantages . The microbial

fuel cell has a great advantage of directly converting the organic waste into electricity,

with high conversion efficiency and efficient operation at optimum conditions.

By the way of anaerobic respiration of organic substrates the microorganisms

present in the anode acts as biocatalyst and generate electrons (e-) and protons (H+). In

the typical MFC the anode and cathode chambers are separated by a membrane and

connected by an external circuit. With microbial decomposition of the organic

substrates with anaerobic conditions generates electrons and protons transferred

through the membrane with an electron acceptor. The availability and high redox

potential, oxygen is the most preferred electron acceptor. In waste water treatment,

desalination, hydrogen production, remote sensing, and pollution remediation and also

as a remote power source are the potential applications of the microbial fuel cell
