Nitrification
Nitrification is the biological conversion of ammonium to nitrate
Nitrification is a two-step process.
In the first step of nitrification, ammonia-oxidizing bacteria oxidize ammonia to nitrite
NH3 + O2 → NO2-+ 3H+ + 2e- (1)
Bacteria known as Nitrosomonas convert ammonia and ammonium to nitrite
