Outline of Final Research Achievements

Nitrous oxide is known as global warming gas as well as the ozone-degrading substance. The recent study suggested the biological nitrogen fixation can also incorporate nitrous oxide into ammonia by the biological reduction. Based on our previous findings showing the bioelectrochemical enhancement of dechlorination of pentachlorophenol and anaerobic nitrogen-fixing microorganisms in the dechlorination consortium, we have conducted this project to find whether biological nitrogen fixation can be accelerated electrochemically for removal of nitrous oxide. The results suggested the successful enhancement of nitrogen fixation bio-electrochemically.
