Nitrogen transformation is central to life on Earth. This project will challenge a century-old paradigm that microorganisms must cooperate in a team to convert nitrogen from organic- to inorganic forms. We will carry out the first-ever systematic investigation of a novel process, where a single organism mediates complete ammonification and ammonia oxidation, directly connecting organic- and inorganic nitrogen. By revealing metabolic pathways, characterising ecophysiological properties, isolating key microorganisms and exploring their application potential, this project will change our fundamental understanding of global nitrogen cycling, improve the sustainability of water management, and contribute to the circular economy transition

氮转化是地球生命的核心。该项目将挑战一个世纪以来的范式，微生物必须在团队中合作，以将氮从有机形式转变为无机形式。我们将对新过程进行有史以来的第一个系统研究，其中单个生物体介导了完全的氨化和氨氧化，直接连接有机氮和无机氮。通过揭示代谢途径，表征生态生理特性，隔离关键微生物并探索其应用潜力，该项目将改变我们对全球氮循环的基本理解，提高水管理的可持续性，并有助于循环经济过渡
