Nitrous oxide production by ammonia oxidizers: Physiological diversity, niche differentiation and potential mitigation strategies
University of Aberdeen · Leibniz University Hannover · +3 more institutions
Abstract
Abstract Oxidation of ammonia to nitrite by bacteria and archaea is responsible for global emissions of nitrous oxide directly and indirectly through provision of nitrite and, after further oxidation, nitrate to denitrifiers. Their contributions to increasing N 2 O emissions are greatest in terrestrial environments, due to the dramatic and continuing increases in use of ammonia‐based fertilizers, which have been driven by requirement for increased food production, but which also provide a source of energy for ammonia oxidizers (AO), leading to an imbalance in the terrestrial nitrogen cycle. Direct N 2 O production by AO results from several metabolic processes, sometimes combined with abiotic reactions.…
