Revealing the microbial process of iron-driven anaerobic ammonium oxidation (2018–2021)
This project aims to gain fundamental understanding of the recently discovered microbially-facilitated process of anaerobic ammonium oxidation that is coupled to iron reduction. This process (called Feammox) is suggested to be responsible for significant nitrogen loss from soil and sediment ecosystems, resulting in pollution of the atmosphere and our water systems. In the project, the Feammox microorganisms will be enriched and then characterised to reveal the metabolic details of the iron reduction and ammonium oxidation pathways. This will improve understanding of ecosystem nitrogen flux and benefit the management of nitrogen fertilizers used to meet the food and energy requirements of the worldâ€¿s growing populations.
