Unique Directionality and Metabolic Modeling of Nitrous Oxide and Nitric Oxide Emissions from Nitrification
Abstract:The overarching goal of this study was to elucidate the molecular mechanisms of nitrous oxide (N2O) and nitric oxide (NO) emissions from nitrification in response to transient anoxia and to develop mathematical constructs to describe the underlying nitrogen transformations. Using pure-cultures of Nitrosomonas europaea 19718, it was determined that N2O emissions from nitrification are a manifestation of a recovery from anoxic transients and not a direct response to imposition thereof. Furthermore, a drastic imbalance in expression of four principal genes involved in N-redox reactions was attributed to the mutually distinct production of N2O and NO. A structured mathematical model to was describe these phenomena was developed and subjected to preliminary calibration.
