What Is Denitrification? | Fluence

Definition of Denitrification. Denitrification is the reduction process, where the nitrate is removed in the form of nitrogen and is converted to nitrogen gas. The action is performed by bacteria like Bacillus, Aerobacter, Lactobacillus, Spirillum, Pseudomonas. The bacteria are heterotrophs, and the action is completed under anaerobic condition.

Nitrification Denitrification

O), and, in turn, nitrogen gas (N 2). Since nitrogen gas has low water solubility, it escapes into the atmosphere as gas bubbles. Free nitrogen is the major component of air, thus its release does not cause any environmental concern. The formula describing the nitrification reaction follows: 6NO 3 + 5CH 3 OH 3N 2 + 5CO 2 + 7H 2 O + 6OH’

What is Nitrification

Simultaneously, denitrification occurs wherein nitrate is converted to nitrite then to ammonia which when acted upon by Bacillus, Psuedomonas and Clostridium, are converted into nitrogen gas, nitrous oxide and nitric oxide, all nontoxic, and are released in the process.

Denitrification is the conversion of nitrate (NO3) to nitrogen gas (N2). How is this done? Heterotrophic bacteria utilize the nitrate (NO3) as an oxygen source under anoxic conditions to break down organic substances.

The Nitrogen Cycle

The final aspect of the nitrogen cycle is the process of denitrification. This process is performed by a variety of microscopic bacteria, fungi, and other organsims. Nitrates in the soil are broken down by these organsisms, and nitrogen is released into the atmosphere. This complete the cycle.

Denitrification an overview | ScienceDirect Topics

Denitrification occurs in moderately reduced environments in the absence of oxygen and is one of the dominant metabolisms involved in removal of nitrogen from many terrestrial and aquatic ecosystems (Burgin Hamilton, 2007; Devol, 2015).The denitrification process converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.

Nitrogen in the Environment: Denitrification

The conditions that cause denitrification can have positive as well as negative implications on water quality. The positive implication is that denitrification converts nitrates (NO) to nitrogen gas, resulting in a net loss of nitrate from the soil system. The negative aspect of denitrification is that it takes place in soils that are waterlogged.
