Nitrification - Wikipedia
WebNitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil. The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.
The Nitrogen Cycle: Processes, Players, and Human Impact
WebNitrification is the process that converts ammonia to nitrite and then to nitrate and is another important step in the global nitrogen cycle. Most nitrification occurs...
Nitrification - an overview | ScienceDirect Topics
WebNitrification is a microbially-catalyzed process whereby ammonia (NH 3) is oxidized to nitrite (NO 2 −) and subsequently to nitrate (NO 3 −). It is also responsible for production of nitrous oxide (N 2 O), a climatically important greenhouse gas. Because the microbes responsible for nitrification are primarily autotrophic, nitrification ...

5.10E: Nitrification - Biology LibreTexts
WebDec 24, 2022 · Nitrification is the net result of two distinct processes: oxidation of ammonium to nitrite (NO 2−) by nitrosifying or ammonia-oxidizing bacteria and oxidation of nitrite (NO 2−) to nitrate (NO 3−) by the nitrite-oxidizing bacteria. Nitrification is an important step in the nitrogen cycle in soil.

WebFeb 17, 2023 · Nitrification is an essential step in the nitrogen cycle of soil, water, and wastewater treatments. It involves the biological oxidation of ammonia (NH 3) or ammonium (NH 4 +) to nitrite (NO 2 –) and then from nitrite (NO 2 –) to nitrate (NO 3 –). Thus it involves two steps, as shown below.

Nitrifying bacterium | Nitrification, Nitrifiers, Nitrogen Cycle
WebThe nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites ( Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates ( …
What is Nitrification? An Overview and Process of Nitrification
WebNitrification is the natural process that occurs in the environment by specialised autotrophic bacteria. During this aerobic process, ammonia is converted to nitrites (NO2-) and then nitrates (NO3-). A group of specialised gram-negative, rod-shaped chemoautotrophic bacteria are called Nitrosomonas.
