denitrifikacja
Denitryfikacja is a biological process that converts nitrate (NO3-) into nitrogen gas (N2). This process is carried out by a diverse group of microorganisms, primarily bacteria, known as denitrifiers. These organisms are facultative anaerobes, meaning they can respire using oxygen when it is available, but switch to using nitrate as an electron acceptor when oxygen is scarce. This typically occurs in environments with low oxygen concentrations, such as saturated soils, sediments, and wastewater treatment systems.
The overall process involves several steps, each catalyzed by specific enzymes. Nitrate is sequentially reduced to
Denitrification plays a significant role in both natural and engineered environments. In agriculture, it can lead
