Environmental and kinetic controls on aerobic heterotrophic denitrification and N2O emission in acidic aerated biofilms.
Acidic, nitrite-rich aerobic systems are emerging hotspots for substantial N2O and NO emissions. Aerobic denitrification has been implicated as a major driver, but the controls governing its occurrence and persistence remain poorly understood. We provide direct experimental evidence that aerobic heterotrophic denitrifi...
