Anaerobic methane oxidation: high-rate performance of a continuous bioreactor using nitrate and nitrite as electron acceptors

This study demonstrates the possibility of simultaneously eliminating dissolved CH4 and nitrate/nitrite in a high-rate continuous CSTR under entirely anaerobic conditions. The bioreactor was inoculated with previously acclimated inoculum consisting of 50/50% anaerobic granular and activated sludges.
