Bioelectrochemical System: An Eco-Friendly Approach to Generate Electricity-Utilizing Plants and Microorganisms

Abstract

Owing to the fact of future energy demand, and the clampdown world is facing now, there is a crucial requirement for the sustainable energy sources which are cheap and environmentally friendly.As committed by a green alternative, for future enhancement of the planet, the fossil fuel abandonment is required, and instigation of renewable resources such as Microbial Fuel Cell [MFCs] and Plant Microbial Fuel Cell [PMFCs] should be implemented. MFC is a visionary technique, as it converts wastage into the energy, whereas, PMFC is a new-fangled technique devoid of any climatic conditions and it requires less investment. By scrutinizing this technique, Bacillus megaterium and sewage material are used in MFCs, whereas Azolla and Trigonellafoenumis used in PMFCs, which converts chemical energy into electrical energy with the help of electrons flowing from the anode to cathode via circuit. The individual setup of each MFCs and PMFCs are examined diurnally for voltage and current gain proceeded by connecting both [MFC and PMFC] in series with LED between, thus gaining the luminance in LED.The yield in voltage and current were measured for different fuel cells from Day 1 to Day 12 and Obtained notable difference in both voltage and current. Voltage Difference: MFC;0.041 to 1.733,BMFC;0.271 to 1.885, PMFC(Azolla); 0.00 to 0.35, PMFC(Fenugreek); 0.01 to 0.766 and Current difference: MFC; 0.001-1.133, BMFC; 0.001-1.133, PMFC(Azolla); 0.00 – 0.2, PMFC(Fenugreek); 0.00 – 0.512.The assurance in the aptness of this process, can be evaluated by its exertion in the society. As known its major application is production of electricity from the organic as well as inorganic waste in the environment, and by the plants. Majority of the industries have gone through this manner for the bioenergy and biosensors production and wastewater treatment.
