A novel microbial process breaking through the nitrogen cycling

点击翻译按钮获取中文摘要

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
