Revealing the microbial process of iron-driven anaerobic ammonium oxidation

该项目旨在获得对最近发现的微生物促进厌氧氨氧化过程的基本理解，该过程与铁还原有关。这一过程（称为Feammox）被认为是土壤和沉积物生态系统中大量氮流失的原因，导致大气和水系统污染。在该项目中，将对Feammox微生物进行富集和表征，以揭示铁还原和铵氧化途径的代谢细节。这将增进对生态系统氮通量的了解，并有利于氮肥的管理，以满足世界上不断增长的人口对粮食和能源的需求。

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 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 world’s growing populations.
