Question:
Bacteria that oxidise Ammonia to Nitrite
Bacteria that oxidise Ammonia to Nitrite
Show Hint
In nitrification, ammonia is first oxidized to nitrite by bacteria like Nitrosomonas and Nitrococcus. Remember key players in the nitrogen cycle.
Updated On: Jun 3, 2025
- Pseudomonas
- Rhizobium
- Nitrococcus
- Thiobacillus
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Nitrococcus is a nitrifying bacterium that plays a role in the oxidation of ammonia to nitrite, which is a key step in the nitrogen cycle. Pseudomonas and Rhizobium do not perform this oxidation step. Thiobacillus is involved in sulfur oxidation, not nitrogen oxidation.
