Question

Write differnt bbetween nitrification and denificatiion

Answer 1

The breakdown of nitrates by bacteria (mainly Paracoccus denitrificans) - it is part of the Nitrogen Cycle.
The nitrates are converted to nitrogen gas. This makes the soil less fertile.
Denitrification can be used to remove harmful levels of nitrates from the water supply.

Nitrification is an aerobic process in which ammonia or nitrite serve as electron-donor substrates and oxygen serves as the electron acceptor. Bacterial species like Nitrosomonas oxidise ammonia to nitrite using molecular oxygen. Next bacterial species like Nitrobacter oxidise nitrite to nitrate. These organisms need oxygen and grow chemolithoautotrophically (= using the nitrogen compounds as energy source and carbon dioxide as carbon source).

Answer 2

Nitrification is the biological oxidation of ammonia or ammonium to nitrite by the oxidation of nitrite to nitrate.
The loss or removal of nitrogen compounds specifically reduction of nitrates by bacteria...
