Microbial metabolism in a mixed culture anode of microbial fuel cell fed with mixed sources of organic carbon largely resembles the metabolism found in anaerobic environments (digesters, sediments) where CH4 is the end product instead of electrical current. It is hypothesized that current generation is a viable competitor to steer or control CH4 emissions from (cultivated) wetlands. It has already been shown that a plant-MFC is capable of efficiently converting organic carbon derived from rhizodeposition into an electrical current. To understand the interaction between methanogenic metabolism and current generation in waterlogged sediments, several microcosm studies have been carried out
