This text book on Microbial Fuel Cell"[MFC], Which embodies a different kind of sustainable power by producing energized power broadly by the means of different types of wastes such as industrial wastes, water wastes, plant and animal wastes and so on. The MFC not only has the potential to treat waste water for recycle and produce energized power, by bringing two progressively limited sustenance, but also develops capacity of the terminal linked with microbes to vitiate waste and venomous chemicals. Thus, a deeper focus towards a clear understanding of the microbial processes involved in the MFC systems would mark a better and a faster improvement towards the various applications of Microbial Fuel Cell. The text is supported by a number of solved and unsolved examples to enhance the problem-solving skills of the research students. Besides, various universities' research questions and quiz are also provided with answers.
