Study Notes
Types of Organisms Based on Oxygen Requirements
- Obligate (strict) aerobes are organisms that depend on oxygen for aerobic respiration and cannot survive without it.
- Facultative anaerobes are versatile organisms that can grow in both oxygen-rich and oxygen-poor environments, utilizing aerobic respiration when oxygen is available and switching to fermentation or anaerobic respiration in its absence.
- Aerotolerant anaerobes do not require oxygen for growth and can thrive in its presence without being negatively affected; they primarily rely on fermentation.
- Microaerophiles need lower than atmospheric levels of oxygen to survive, and excessive oxygen can be harmful to these organisms.
- Obligate (strict) anaerobes are organisms that cannot tolerate oxygen at any concentration, as even trace amounts can be lethal to them.
- Capnophiles specifically thrive in environments with elevated carbon dioxide levels, requiring this gas for optimal growth and survival.
