Webb27 sep. 2024 · Denitrifying bacteria As the nitrogen cycle is a cycle, the nitrogenous compounds must be returned to the atmosphere as N 2. Denitrifying bacteria are a type of anaerobic bacteria which convert nitrates to N 2 during respiration. This stage is known as denitrification Figure 1: The main three types of bacteria involved in the nitrogen cycle WebbThe denitrifying bacteria convert nitrates to nitrogen gas and release it into the atmosphere. Human Influences and their Consequences The nitrogen cycle continues to proceed in the normal way if left undisturbed. However, many activities of man cause considerable disturbances in the nitrogen cycle. john bramhall san francisco

Webb25 jan. 2024 · Q.4. What is the difference between nitrification and denitrification? Ans: Nitrification and denitrification are the two important processes of the nitrogen cycle. In the process of Nitrification, nitrifying bacteria oxidise ammonia to nitrite which is further oxidised into nitrate. On the other hand, denitrification is the opposite of ...
