Detailed explanation-1: -Anaerobic bacteria are widely distributed in nature in oxygen-free habitats. Many members of the indigenous human flora are anaerobic bacteria, including spirochetes and Gram-positive and Gram-negative cocci and rods.

Detailed explanation-2: -Anaerobes are microorganisms that don’t require oxygen in order to survive or proliferate. Instead of oxygen, anaerobic organisms use electron acceptors such as nitrate or sulfate and other inorganic acceptors that have a lower reduction potential than oxygen, thus resulting in less efficient respiration.

Detailed explanation-3: -Facultative anaerobes are bacteria that can grow in both the presence or absence of oxygen. In addition to oxygen concentration, the oxygen reduction potential of the growth medium influences bacterial growth.

Detailed explanation-4: -Obligate anaerobes (microorganisms that live and grow in the absence of molecular oxygen) will die when exposed to atmospheric levels of oxygen. Facultative anaerobes can use oxygen when it is present.
