Bacteria that utilize oxygen for growth and oxygen-based metabolism (e.g. aerobic respiration).
Some bacteria are obligate aerobes that they require oxygen for aerobic respiration. Others can switch to anaerobic methods if oxygen is not present.
Examples of aerobic bacteria are Nocardia sp., Psuedomonas aeruginosa, Mycobacterium tuberculosis, and Bacillus sp.
Also called: aerobe.
