    Question

    Which one of the following micro-organism oxidizes

    nitrite to nitrate?
    A Nitrosomonas Correct Answer Incorrect Answer
    B Azotobacter Correct Answer Incorrect Answer
    C Clostridium Correct Answer Incorrect Answer
    D Nitrobacter Correct Answer Incorrect Answer

    Solution

    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.
