Azotobacter is a genus of free-living, aerobic, and non-symbiotic bacteria that can fix atmospheric nitrogen into ammonium ions, which are then available to plants. While the enzyme responsible for nitrogen fixation (nitrogenase) is typically sensitive to oxygen, Azotobacter uses a high metabolic respiration rate to protect the enzyme from oxygen damage while remaining an aerobe.
