An anaerobe is an organism that thrives in an environment without oxygen. Facultative anaerobes prefer an oxygen-free environment but can survive in the presence of oxygen. Obligate anaerobes are destroyed by oxygen and cannot survive if it is present in their environment.
An obligate anaerobe.
Bacillus subtilis is a facultative anaerobe, meaning it can grow in the presence or absence of oxygen.

Facultative anaerobes does not need o2 to grow but can also grow with o2. Obligate anaerobe cannot grow at all in the presence of o2.
Yes, salmonella is a facultative anaerobe, meaning it can survive in both oxygen-rich (aerobic) and oxygen-poor (anaerobic) environments.
Faculatitive Anaerobe
It is neither, since it is not living.

A facilitative anaerobe is a type of microorganism that can grow in the presence or absence of oxygen but prefers oxygen when it is available. These organisms have the ability to switch between aerobic and anaerobic metabolism depending on the environmental conditions.
Streptococcus is an obligate anaerobe and therefore lacks catalase. However, Streptococcus would be considered an aerotolerant anaerobe because, even though it lacks catalase to break down hydrogen peroxide, it also lacks the cytochrome system that would produce hydrogen peroxide in the first place. Therefore, it is not aerobic, but it is tolerant of aerobic conditions.
No. Escherichia coli is considered to be a facilitative anaerobe.
Yes, Serratia is a facultative anaerobe and can ferment lactose.
