Facultative anaerobic organism

A facultative anaerobe is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation if oxygen is absent.

Some examples of facultatively anaerobic bacteria are Staphylococcus spp., Streptococcus spp.,[1] Escherichia coli, Salmonella, Listeria spp.[2], Shewanella oneidensis and Yersinia pestis. Certain eukaryotes are also facultative anaerobes, including fungi such as Saccharomyces cerevisiae[3] and many aquatic invertebrates such as Nereid (worm) polychaetes.[4]
