A review of a sustainable bio-electricity generation from microbes grown in waste water

Abstract

Abstract The high growth of world population, increase global urbanization and rapid rise of industrialization have driven a drastic escalation in demands not only for food, and water but also energy. In addition to decreasing the natural oil reserve, excessive utilization of fossil fuel for the conversion into various forms of energy, including electrical power, also contributes to atmospheric pollution due to the release of gases from combustion which eventually will cause climate change. Consequently, recent years, great attention has been focused on energy production and generation from microalgae, because it is sustainable, environmentally friendly and economical. Microalgae fuel cell (MFC) is a device which utilizes microalgae capable of oxidizing organic matter by generating electron, obtaining energy for their own and providing electricity generation. Wastewater contains inorganic and organic nutrients which could be used as the source of substrate for microalgae to grow. A combination of MFC and wastewater would offer a great promising technology in the future for the simultaneous treatment of wastewater and electricity generation. This paper review the potentials of electrical energy generation with the application of MFC, the concept of MFC and the current development of MFC.
