Study Notes
Microbial Growth and Oxygen Requirements
-
Obligate Anaerobes: Cannot survive in the presence of oxygen. Lack enzymes (catalase and superoxide dismutase) to detoxify oxygen byproducts. Example: Clostridium tetani.
-
Obligate Aerobes: Require oxygen for growth. Example: Mycobacterium tuberculosis.
-
Facultative Anaerobes: Can grow with or without oxygen. Grow best in the presence of oxygen. Most bacterial species fall into this category.
-
Microaerophiles: Require a small amount of oxygen for growth.
