WebDenitrification is a response to changes in the oxygen (O 2) concentration of their immediate environment. Only when O 2 is limited will denitrifiers switch from aerobic respiration to anaerobic respiration, using nitrite (NO 2) as electron acceptor.

Anaerobic denitrification coupled to methane oxidation was first observed in 2008, with the isolation of a methane-oxidizing bacterial strain found to oxidize methane independently. This process uses the excess electrons from methane oxidation to reduce nitrates, effectively removing both fixed nitrogen and methane from aquatic systems in habitats ranging from sediment to peat bogs to stratified water columns. WebDec 24, 2024 · Many different types of electron acceptors may be used for anaerobic respiration. Denitrification is the utilization of nitrate (NO 3−) as the terminal electron acceptor. Nitrate, like oxygen, has a high reduction potential. This process is widespread, and used by many members of Proteobacteria.
