It is a facultative anaerobic organism.
Explanation:
This organism makes ATP (energy provider molecule) by aerobic respiration in presence of oxygen, but when oxygen is removed it is capable of switching to fermentation (sugar consumption increases and growth rate decreases).
This happens because fermentation is much less effective at producing ATP and therefore there is not enough energy for growth.
This organisms are called facultative anaerobic.
Organisms with this type of metabolism include bacteria like Escherichia coli and Salmonella or yeast like Saccharomyces cerevisiae.
