Within a NEDO project involving Sekisui, Panasonic and others, Professor Kazuya WATANABE of Tokyo University of Pharmacy and Life Sciences has developed a novel waste water treatment plant based on Shewanella oneidensis. This organism forms conducting nanomaterials outside its cell wall and adheres to electrode material thus permitting the construction of a waste water-driven biofuel cell. A laboratory prototype achieved 1.3 kg-COD m3/day at a residence time of 9 hours.
