Ammonia-oxidizing archaea are present in large numbers in the ocean(1-3) and soils(4-6), suggesting a potential role for archaea, in addition to bacteria, in the global nitrogen cycle(7,8). However, the importa
The oxidation of ammonia to nitrate, known as nitrification, is a key process in the nitrogen cycle. Real-time polymerase chain-reaction measurements show that nitrification is driven by bacteria rather than archaea in nitrogen-rich grassland soils in Ne

Nitrogen Cycle The nitrogen cycle is the series of biogeochemical transformations in which the element nitrogen is transferred among organisms and nonliving reservoirs such as the soil, the oceans, and the atmosphere. Nitrogen is an essential element for all living things because it is a principal ...

an exchange of resources between the biotic (living) and abiotic (non-living) portions of the ecosystem; in order to ensure survival. The following processes can be included as a biogeochemical cycle: photosynthesis, cellular respiration, water cycle, phosphorus cycle and lastly the nitro...
Nitrifying Bacteria (Oxidation of Ammonia to Nitrite and Then Nitrate) The half-reactions of thenitrifying bacteriamake up the oxidativearmof the nitrogen cycle (Table 3). The recently discovered chemolithotrophic anaerobic ammonia oxidizing (ANAMOX) bacteria generate energy in a series of reactions ...
Anaerobic ammonium oxidation (anammox) bacteria contribute significantly to the global nitrogen cycle and play a major role in sustainable wastewater treatment. Anammox bacteria convert ammonium (NH4+) to dinitrogen gas (N2) using intracellular electron acceptors such as nitrite (NO2−) or nitric oxi...

How Do Nitrogen Fixing Bacteria Help Cycle Nitrogen Through Ecosystems?N-fixing bacteria participate in N-circulation through the ecosystems by catching it from the air and adjusting for plant needs (fixation of nitrogen). Then, crops use it for growth (N-assimilation). Further on, when plants ...
