Summary

NOx are environmental pollutants that lead to the formation of acid rain and tropospheric ozone. They are released from many different sources, including, for example, agriculture and wastewater treatment plants. Besides non-biological alternatives, NOx can also be eliminated biologically, under cost-efficient conditions. Different bioreactor configurations have been evaluated for NOx removal, such as the rotating drum bioreactor, the hollow fiber membrane bioreactors, BioDeNOx systems and photobioreactors, as well as some integrated, multi-steps systems. N2O removal has mainly been studied with bioelectrochemical reactors, biofilters and biotrickling filters. N2O is an important gas found in emissions at wastewater treatment plants. Overall, microbial reduction of NO/N2O merits further study, as a potential means of removal of NOx.
