Microbial Fuel Cell -Production of Bio Electricity
Electricity is a form of energy resulting from charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current. Microorganisms are ubiquitous and are used in almost all industries to produce specific products. They are termed as "the degraders" of the environment. They utilize a wide range of substrates in order to survive. This property is harnessed for the production of electricity. The biochemical interactions are converted into electricity. They act as catalysts for the production of electricity utilizing a wide range of substrate which helps generate power. Microorganisms were isolated from air and water sources. It was identified based on morphology and further confirmed by biochemical tests. Isolated organisms were examined for electricity production. Standardization procedures were carried out for increasing the efficiency of electricity production. Sewage water was used as media in which organism were grown which transformed the substrate into electricity and in the process the sewage was treated and the water was clarified. The MFC generated Alternating Current (AC). It cannot be used directly hence it was converted into Direct Current (DC) with the help of a capacitor. A battery like device was used to store the produced electricity. This was used to operate small gadgets like the LED bulb.
