Aerobic Bacteria


Definition - What does Aerobic Bacteria mean?

In plants, aerobic bacteria refer to a type of bacteria that requires oxygen to survive and thrive. By contrast, anaerobic organisms do not require any oxygen. Some types of anaerobic bacteria may even die if exposed to oxygen. Aerobic bacteria often live in topsoil because the air pockets provide plenty of oxygen.

In vermiculture, growers normally differentiate between four main types of aerobic microorganisms:

  • Aerotolerant anaerobes: These microorganisms are unharmed by oxygen, but unlike other aerobic bacteria, they do not use oxygen either.
  • Microaerophiles: This type of bacteria does require oxygen to produce energy. They can easily be harmed by the atmospheric concentration of oxygen.
  • Facultative anaerobes: These anaerobes do convert oxygen into energy when oxygen is available. When not exposed to oxygen, facultative anaerobes produce energy by using anaerobic methods.
  • Obligate aerobes: Through cellular respiration, obligate aerobes oxidize substrates through oxygen absorption. For example, they can generate energy using both fats and sugars.
