Combined anaerobic ammonium and methane oxidation for nitrogen and methane removal
Résumé
Anammox (anaerobic ammonium oxidation) is an environment-friendly and cost-efficient nitrogen-removal
process currently applied to high-ammonium-loaded wastewaters such as anaerobic digester effluents.
In these wastewaters, dissolved methane is also present and should be removed to prevent greenhouse
gas emissions into the environment. Potentially, another recently discovered microbial pathway, n-damo
(nitrite-dependent anaerobic methane oxidation) could be used for this purpose. In the present paper, we
explore the feasibility of simultaneously removing methane and ammonium anaerobically, starting with
granules from a full-scale anammox bioreactor. We describe the development of a co-culture of anammox
and n-damo bacteria using a medium containing methane, ammonium and nitrite. The results are discussed
in the context of other recent studies on the application of anaerobic methane- and ammonia-oxidizing bacteria for wastewater treatment.
