“ Candidatus Methanoperedens nitroreducens” is an anaerobic archaeon which couples the reduction of nitrate to the oxidation of methane. This microorganism is present in a wide range of aquatic environments and man-made ecosystems, such as paddy fields and wastewater treatment systems. In such environments, these archaea may experience regular oxygen exposure. However, “ Ca . Methanoperedens nitroreducens” is able to thrive under such conditions and could be applied for the simultaneous removal of dissolved methane and nitrogenous pollutants in oxygen-limited systems. To understand what machinery “ Ca . Methanoperedens nitroreducens” possesses to counteract the oxidative stress and survive, we characterized the response to oxygen exposure using a multi-omics approach.
