Abstract Background Increasing attention has recently been devoted to the anaerobic ammonium oxidation (anammox) in eutrophic lakes due its potential key functions nitrogen (N) removal for eutrophication control. However, successful enrichment of anammox bacteria from lake sediments is still challenging, partly ecological interactions between and denitrifying across such with remain unclear. Results This study thus designed fill knowledge gaps using bioreactors enrich more than 365 days. We continuously monitored influent effluent water, measured denitrification efficiencies, quantified bacteria, as well related N cycling genes. found that maximum efficiencies NH 4 + NO 2 − reached up 85.92% 95.34%, respectively. Accordingly, diversity decreased significantly enrichment, relative dominant (e.g., Candidatus Jettenia) Thauera, Afipia ) shifted considerably. The cooperation tended increase microbial community stability, indicating a coupling bacteria. Moreover, nirS -type denitrifiers showed stronger nirK during enrichment. Functional potentials depicted by metagenome sequencing confirmed denitrification. Metagenome-assembled genomes-based model indicated most could provide various materials amino acid, cofactors, vitamin Cross-feeding highlights importance increasing lakes. Conclusions greatly expands our understanding mechanisms among sediments, which sheds new insights into controlling eutrophication.
