Final answer:
Microaerophiles are microbes that grow best at low oxygen levels and prefer environments with lower levels of oxygen than the normal atmospheric conditions.
Step-by-step explanation:
Microaerophiles are microbes that grow best at low oxygen levels.
These bacteria prefer environments with lower levels of oxygen than the normal atmospheric conditions.
They may also have a requirement for increased levels of carbon dioxide.
Microaerophiles make ATP by aerobic respiration and may also ferment sugars aerobically.
