Metagenomic and metatranscriptomic insights into microbial community and nitrogen metabolism in an Anammox-dominated biofilm reactor
This project aims to: (1) investigate the microbial community succession during the enrichment process; (2) reconstruct high-quality metagenome-assembled genomes (MAGs) of key functional populations, including AnAOB, ammonia-oxidizing bacteria (AOB), and denitrifiers; (3) elucidate the metabolic pathways responsible for nitrogen removal, with a focus on the coupling between partial nitrification, endogenous denitratation, and Anammox; and (4) link gene expression patterns to reactor performance via metatranscriptomic analysis. This dataset provides valuable genomic resources for understanding AnAOB ecology and the metabolic interactions within a self-sustaining nitrogen-removing consortium. It supports the development of simplified, energy-saving wastewater treatment processes.
