Nitrogen Kinetic Isotope Effects of Nitrification by the Complete Ammonia Oxidizer Nitrospira inopinata

ABSTRACT Analysis of nitrogen isotope fractionation effects is useful for tracing biogeochemical nitrogen cycle processes. Nitrification can cause large nitrogen isotope effects through the enzymatic oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−) (15εNH4+→NO2- and 15εNO2-→NO3-). The...
