In recent years, new methods of clean and environmentally friendly
energy production have been the focus of intense research efforts.
Microbial fuel cells (MFCs) are devices that utilize naturally occurring
microorganisms that feed on organic matter, like waste water, while
producing electrical energy. The natural habitats of bacteria thriving in
microbial fuel cells are usually marine and freshwater sediments. These
microorganisms are called dissimilatory metal reducing bacteria (DMRB),
but in addition to metals like iron and manganese, they can use organic
compounds like DMSO or TMAO, radionuclides and electrodes as
terminal electron acceptors in their metabolic pathways.(...)Fundação para a Ciência e a Tecnologi
