Nitrobacter is a genus of bacteria that belongs to the Nitrospiraceae family. They are known for their ability to perform nitrification, which involves the oxidation of nitrite (NO2-) to nitrate (NO3-). Nitrosomonas, on the other hand, is responsible for the oxidation of ammonia (NH3) to nitrite in the nitrification process. Azotobacter and Clostridium are not directly involved in nitrification.
