Role of phages in bioreactors for nitrification and anammox

Forskningsprojekt, 2025 – 2028

Nitrogen pollution has doubled since pre-industrial times, leading to problems such as eutrophication and greenhouse gas emissions. Municipal wastewater treatment plants mitigate pollution by
removing reactive nitrogen. Here, microbial communities convert reactive nitrogen into nitrogen gas.
However, the key microorganisms are slow-growing, and the process is energy-intensive and prone to greenhouse gas emissions. This project will improve our understanding of how phages impact the
microbial communities. By studying phage interactions, the project aims to enhance the reliability of nitrogen removal, especially in cold conditions. We will combine field sampling and lab experiments 
to identify phages, track their effects on microbial communities, and explore ways to optimize reactor conditions. The findings could lead to innovative approaches, including phage therapy, to improve
wastewater treatment and reduce environmental impacts.
