Which of the following is a nitrite oxidizing bacteria?
- Nitrosovibrio tenuis
- Nitrospinagracilis
- Nitrosomonas europaea
- All of the above
Hint:
Nitrospinagracilis get their energy from the oxidation of inorganic nitrogen compounds
The correct answer is: Nitrospinagracilis
- Nitrite-oxidizers mainly comprise six bacterial genera: Nitrobacter, Nitrospira, Nitrotoga, Nitrococcus, Nitrospina, and Nitrolancetus, which are affiliated with Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, and Deltaproteobacteria, as well as the phyla Chloroflexi (Nitrolancetus) and Nitrospirae.
