NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Generally, there are different types of anaerobic organisms. Facultative anaerobes (like Escherichia coli) are able to adapt their metabolism and can grow under conditions with or without oxygen but prefer aerobic conditions.

Detailed explanation-3: -The most common examples of the facultative anaerobes are bacteria (e.g., Escherichia coli, Pseudomonas aeruginosa, Staphylococcus spp., Listeria spp., Salmonella, Shewanella oneidensis, and Yersinia pestis), Archaea, certain eukaryotes (e.g., Saccharomyces cerevisiae) and invertebrates, like nereid and polychaetes.

Detailed explanation-4: -Facultative anaerobe definition in biology, a microbe that can produce energy via aerobic respiration but then shift to anaerobic respiration based on the quantity of oxygen and fermentable content present in the environment. The facultative anaerobes examples include E. Coli and yeast.
