Facultative anaerobes Definitions:

  1. Facultative anaerobes are those organisms including yeasts and many bacteria, can make enough ATP to survive using either fermentation or respiration.

  2. Facultative anaerobes use O2 if it is present but can also carry out fermentation or anaerobic respiration in an anaerobic environment.

Facultative anaerobes Explanation:

A facultative anaerobe is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent. An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die in the presence of oxygen. An example of facultative anaerobe is E coli.
