What is nitrification? What are the two steps of the process? Oxidation of ammonia (NH4+) to nitrite (NO2-) and Nitrate (NO3-) 1. ammonia oxidation to nitrite by ammonia-oxidizing bacteria (AOB) NH3 + O2 + ADP + Pi --> NO2- + H+ + ATP 2. nitrite oxidation to nitrate by nitrite-oxidizing-bacteria NO2- + O2 + ADP + Pi --> NO3- + ATP What is the produced ATP used for in the nitrite-oxidizing bacteria (NOBs) ? The ATP is used to fix CO2 in the calvin cycle. This allows for NOBs to grow on...
