Question

Quizplus · Accepted Answer

Bacteria that use oxygen but only at low concentration are called microaerophiles. They grow best under reduced oxygen levels, typically between 2% to 10% oxygen concentration. Obligate aerobes use oxygen for growth and metabolism and require high oxygen levels. Obligate anaerobes cannot tolerate oxygen at all and grow in the absence of oxygen. Aerotolerant anaerobes do not use oxygen for energy, but they can tolerate its presence and grow in its presence.
