ROMERO MEJIA, Alba Ayde; VASQUEZ, Jorge Adrian  and  LUGO GONZALEZ, Armando. Bacteria, source of energy for the future. Tecnura [online]. 2012, vol.16, n.32, pp.118-143. ISSN 0123-921X.

This paper presents a family of bacteria called Geobacter that have the ability to produce power as a renewable source in a microbial fuel cell. These bacteria can completely oxidize organic compounds using different elements or substances as electron acceptors. The paper addresses key features of the bacteria, the mechanisms used to harness the electricity generated and an approximation of the system required to become a competitive source of renewable energy. The results show a comparative analysis of sources of conventional and unconventional energy with respect to the Geobacter family of bacteria.

Keywords : Microbial fuel cell; Electricity; Geobacter; Environmental impact; Organic matter.
