Question

Name an agent which causes denitrification?

Answer 1

Denitrification:

1. Denitrification is known for the reduction of Nitrogen gas by bacteria under anaerobic circumstances, most commonly in microbial mats and sediments.
2. The nitrogen cycle is the process of nitrification & denitrification which regulates nitrogen levels in the atmosphere.
3. Nitrites and nitrates are also transformed into nitrogen in the atmosphere by denitrification.
4. Nitrogen is not returned to the atmosphere without denitrification, therefore it is contained & not recycled.
5. These important compounds, that is essential for the functional and structural growth of entities, will usually not be created if the fixation and hence denitrification does not occur.
6. Denitrifying bacteria are Thiobacillus denitrificans, and Pseudomonas.
