An obligate aerobe is an electron transport chain. Aerobic respiration has the advantage of yielding more energy (adenosine triphosphate or ATP) than fermentation or anaerobic respiration, but obligate aerobes are subject to high levels of oxidative stress.
Examples of obligately aerobic bacteria include Mycobacterium tuberculosis and Nocardia asteroides. With the exception of the yeasts, most fungi are obligate aerobes. Also, almost all algae are obligate aerobes.
