Grows in the presence of atmospheric (free) oxygen
Aerobe
Grows in the absence of atmospheric (free) oxygen
Anaerobe
Cannot grow in the absence of free oxygen, which serves as its final electron acceptor.
Obligate aerobe
Obligate aerobe contains ______, which protects from toxic oxygen.
Superoxide dismutase
Requires reduced amount of free oxygen
Microaerophile
Cannot grow in the presence of atmospheric (free) oxygen
Obligate anaerobe
Final electron acceptor of obligate anaerobe
- Nitrates
- Sulfates
