facultative anaerobe is, simply speaking, an organism which possesses the ability to survive in an environment containing oxygen while growing even more efficiently in an environment without oxygen.
Facultative anaerobes can optionally function without oxygen by two main mechanisms; fermentation and alternate terminal electron acceptors. In fermentation, glycolysis is performed and pyruvate is converted to a fermentation product, reducing NAD + back to NADH. (Note that there are likely many variations on this). The ATP generated from glycolysis is usually the primary ATP source for the cell in these cases. Fermentation products can be used for other biochemical reactions and have various interesting properties. Some common fermentation products include ethanol, lactate, acetate, propionate, and more. With alternate terminal electron acceptors, the electron transport chain still is used, but instead of reducing oxygen, a different molecule is reduced at the end of the chain. Such molecules can include nitrate, fumarate, sulphate, and more. These generally do not allow for the chain to operate as efficiently as it does with oxygen, but it is still sufficient for growth.

hey buddy !! here's your answer...
➡️facultative anaerobes are those microorganisms which are able to live with and without oxygen...
➡️in presence of oxygen the form ATP by aerobic respiration while in absence of oxygen undergo fermentation.
✔️ex. E. coli , Staphylococcus
hope it helps !! ✌️❤️
