Question
What is the function of nitrobacter?
- Conversion of nitrites to nitrates
- Conversion of nitrogen to nitrites
- Conversion of nitrates to nitrogen
- Conversion of ammonia to nitrogen
Hint:
The role of Nitrobacter is Conversion of nitrites to nitrates
The correct answer is: Conversion of nitrites to nitrates
- Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira, and Nitrococcus.
- These bacteria get their energy from the oxidation of inorganic nitrogen compounds.
- Nitrobacter cells are obligate aerobes and have a doubling time of about 13 hours. Nitrobacter play an important role in the nitrogen cycle by oxidizing nitrite into nitrate in soil and marine systems.
