21. Techniques can include reforestation, pest control, nitrification and denitrification, irrigation, coppicing and hedge laying. 22. Members of Nitrospira with the capabilities to perform complete nitrification ( Comammox bacteria ) has also been discovered. 23. It is a nitrification inhibitor and prolongs the availability of nitrogen to both short duration and long duration crops. 24. Ammonia oxidation in autotrophic nitrification is a complex process that requires several enzymes, proteins and presence of oxygen. 25. Nitrification itself is a two-step aerobic process, each step facilitated by a different type of bacteria.26. It can be produced during nitrate assimilation, nitrification , and denitrification; however, it is immediately consumed again. 27. This method occurs by the inactivation of the enzyme via covalent modification of the product, which ultimately inhibits nitrification . 28. A fundamental assumption in this interpretation of the f-ratio is the spatial separation of primary production and nitrification . 29. Near the O2 injection point, a high DO concentration is maintained allowing for nitrification and oxidation of other organic compounds. 30. A partial nitrification process of sewage treatment used for the removal of ammonia and organic nitrogen components from wastewater flow streams.
