What is the role of Ammonia Oxidizing Bacteria (AOB)?

Ammonia Oxidizing Bacteria (AOB) play a crucial role in the nitrogen cycle within wastewater treatment processes. Their primary function is to oxidize ammonia, which is often present in wastewater, into nitrite. This process is essential for reducing the toxic effects of ammonia in the environment and is the first step in the nitrification process.

During this conversion, AOB utilize ammonia as an energy source, thereby helping to transform it into less harmful forms. This oxidation not only mitigates the risks associated with ammonia pollution but also sets the stage for further biological processes that eventually lead to the conversion of nitrite into nitrate by other bacteria. The role of AOB is thus foundational in maintaining water quality and enabling the efficacy of wastewater treatment systems.
