Examples of facultative anaerobes. A common facultative anaerobe is yeast used in various cooking applications such as making bread or beer. In either case this facultative anaerobe must function without oxygen. Yet the yeast can still survive and must for these products to come out right.
In bread yeast is responsible for making the bubbles in the dough. 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.
1 escherichia coli salmonella listeria spp 2 shewanella oneidensis and yersinia pestis. There are many different facultative anaerobes but the most interesting from a health standpoint are pathogens or microbes that cause disease. Bacteria species including salmonella species.
Facultative anaerobes can change their metabolic processes depending on the presence of oxygen using the more efficient process of respiration in the presence of oxygen and the less efficient process of fermentation in the absence of oxygen. Examples of facultative anaerobes include e. There are many different facultative anaerobes but the most interesting from a health standpoint are pathogens or microbes that cause disease.
Bacteria species including salmonella species shigella and escherichia coli e. Coli are the most familiar examples of facultative anaerobes. All of these bacteria are associated with infection of the digestive system.
Facultative anaerobes can live with or without oxygen and because of that they can be found in many places and not all are bacteria. An example of a facultative anaerobe is e. Coli which is found in the large intestine of vertebrates such as humans.
Anthracisis a non motile facultative anaerobe and produces an exotoxin. Anthrax can result in central nervous system. The organism is a facultative anaerobe and is catalase positive and motile.

Among the facultative anaerobes there are many bacteria but also many eukaryotes for example the fungus saccharomyces cerevisiae. Many species of aquatic invertebrates are also considered facultative anaerobes for example many types of polychaetes or marine worms. Aerobic and anaerobic respiration in facultative anaerobic bacteria.
Metabolism refers to a set of chemical reactions that convert food material into energy. For facultative anaerobes respiration pathways shift depending on the presence or absence of oxygen. The following are the steps for the two processes.
Some examples for facultative anaerobes are staphylococcus spp streptococcus spp escherichia coli salmonella listeria corynebacterium and shewanella oneidensis.
