NEET BIOLOGY

Detailed explanation-1: -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-2: -E. coli is a metabolically versatile bacterium that is able to grow under aerobic and anaerobic conditions.

Detailed explanation-3: -Escherichia coli is a metabolically versatile bacterium that is able to grow in the presence and absence of oxygen. To achieve this, it exploits a flexible biochemistry in which aerobic respi-ration is preferred to anaerobic respiration, which in turn is preferred to fermentation.

Detailed explanation-4: -Some examples of facultatively anaerobic bacteria are Staphylococcus spp., Escherichia coli, Salmonella, Listeria spp., Shewanella oneidensis and Yersinia pestis.

Detailed explanation-5: -Facultative anaerobes are bacteria that can grow in both the presence or absence of oxygen. In addition to oxygen concentration, the oxygen reduction potential of the growth medium influences bacterial growth.
