Steady-State Oxygen Isotope Effects of N2O Production in Paracoccus denitrificans

Knowledge of isotopic discrimination, or fractionation, by denitrifying bacteria can benefit agricultural fertilizer management, wastewater treatment, and other applications. However, the complexity of N transformation pathways in the environment and the sensitivity of denitrification to environmental conditions warrant better isotopic distinction between denitrification and other processes, especially for oxygen isotopes. Here, we present a dataset of δ¹⁸O measurements in continuous culture of Paracoccus denitrificans. The authors hope that it will be useful in further studies of N₂O in the environment.
