| 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.
