This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $625,065 to the Woods Hole Oceanographic Institution (WHOI) to conduct research on how micronutrient limitations, specifically iron and copper, impact the physiology and nitrous oxide production of ammonia oxidizing bacteria and archaea. The project aims to use stable isotopes of nitrogen and oxygen as tools to investigate how the availability of these key metals influences the growth, metabolism, and nitrous oxide production of these ammonia oxidizing microorganisms. Through a series of batch and continuous culturing experiments and the application of stable isotope techniques, the research seeks to help disentangle the underlying controls on nitrous oxide production during the nitrification process, with potential implications for water quality, ecosystem health, wastewater management, agriculture, and climate change. The award period runs from August 1, 2024 to July 31, 2027.
