Nitrogen and overall cell reaction
Nitrogen fixation is the process by which atmospheric nitrogen gas is converted into salts of nitrogen such as, ammonia, nitrate and nitrogen dioxide image1001 although ammonia (nh3) is the direct product of this reaction, it is quickly ionized to ammonium (nh4+). Engineering analysis of the stoichiometry of photoautotrophic, autotrophic, and heterotrophic removal of ammonia–nitrogen relationships using half-reaction . Recall half-reaction method (units are moles): overall molar stoichiometry for complete nitrification: oxidation level of cell nitrogen = -3, same as ammonia .
