Aerobic bacteria are again divided into two classes depending on oxygen requirement: Facultative aerobes. Obligate or strict aerobes. Facultative aerobes are primarily aerobes but they can also survive in conditions with the absence of oxygen. WebThese findings suggest obligate aerobes are most vulnerable to disruptions in pH homeostasis that promote alkalization when conditions are present that promote optimal respiration (e.g., high oxygen and high nutrients), and they are vulnerable to acidification when conditions limit respiration (e.g., low oxygen and low nutrients).
