Detailed explanation-1: -These organisms can survive in either presence as well as the absence of molecular oxygen and oxygen does not kill these organisms. Staphylococcus spp, Streptococcus spp., Escherichia coli, Salmonella, Listeria, Corynebacterium, and Shewanella oneidensis are some of the bacteria that grow facultatively.

Detailed explanation-2: -Facultative and Microaerophile aerobes: Facultative bacteria behave both aerobically and anaerobically, according to the prevailing conditions. In reduced environments, they acquire energy via anaerobic pathways, whereas in oxidative environments, they develop aerobic pathways.

Detailed explanation-3: -The model organism Escherichia coli is a facultative anaerobic bacterium, i.e. it is able to grow in both aerobic and anaerobic environments. To do so, cells need to be able to adapt to changes of the growth conditions.

Detailed explanation-4: -These are bacteria that, under normal circumstances, breathe anaerobically. But can breathe aerobically when oxygen is available. Rhodopseudomonas is an example of facultative aerobes.
