ABSTRACT
Microbial fuel cells have received increased attention as a means to produce “green” electricity from natural substances such as carbohydrates, agricultural wastes or dairy waste. A microbial fuel cell is a biological system in which bacteria do not directly transfer their produced electrons to their electron acceptor, rather transported over an anode, conducting wire and a cathode. It is divided into two halves: aerobic and anaerobic. The aerobic half has a positively charged electrode and is bubbled with oxygen. The anaerobic half does not have oxygen, allowing a negatively charged electrode to act as the electron receptor for the algal processes. The cathode chamber was sterilized and then refilled with basal medium with Chlorella vulgaris as inoculom to provide electron that transferred from cathode to anode for electricity production. The electricity producing bacteria are known as electrogens. Proton conductive materials in an MFC should ideally be able to inhibit the transfer of other materials such as the fuel (substrate) or the electron acceptor (oxygen) while conducting protons to the cathode at high efficiency. Thus bacterial energy is directly converted into electrical energy. The potential between the respiratory system and electron acceptor generates the current and voltage needed to make electricity. The electrons and protons react with oxygen molecules in the cathode chamber to form water. In nutshell, the novel reactor design and idea of using photosynthetic algae for oxygen supply to cathodic reaction green are also helpful in CO2 sequestration.
