Detailed explanation-1: -Anaerobic bacteria are germs that can survive and grow where there is no oxygen. For example, it can thrive in human tissue that is injured and does not have oxygen-rich blood flowing to it. Infections like tetanus and gangrene are caused by anaerobic bacteria.

Detailed explanation-2: -The 3 anaerobes commonly isolated are Fusobacterium, Prevotella, and Bacteroides.

Detailed explanation-3: -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-4: -Anaerobes, on the other hand, cannot grow in the presence of oxygen. Oxygen is toxic for them, and they must therefore depend on other substances as electron acceptors.
