Nitrogen-fixing bacteria role
WebbFree-living nitrogen-fixing bacteria fix nitrogen by reducing gaseous nitrogen in the air to ammonia. This is incorporated into organic compounds which can be used by plants. An enzyme complex called nitrogenase catalyses this reaction. Nitrogenase activity is sensitive to the presence of oxygen.
