What is faculative anaerobe and aerotolerant anaerobe?


What is faculative anaerobe and aerotolerant anaerobe?

Step 1

Prokaryotic organisms require different environmental conditions for their survival. Some prokaryotic organisms survive in aerobic conditions and some survive in anaerobic condition, while some require different concentrations of oxygen to thrive.

Step 2

Facultative anaerobes can survive in both absence as well as presence of oxygen. They can produce ATP by aerobic respiration in presence of oxygen also able to switch to fermentation in absence of oxygen. Yeast is a common facultative anaerobe. Example: Saccharomyces cerevisiae.

Step 3

Aerotolerant anaerobes are the organisms that produce ATP through fermentation. They do not use oxygen for ATP production, but these anaerobe...
