Autotrophic OrganismsAlso known as autotrophs.
Organisms that use inorganic materials for energy and growth.
|
AnoxicA condition in which dissolved (atmospheric) oxygen is deficient, however, oxygen is available in the combined form (e.g., nitrate, sulfate and carbonate).
|
Anaerobic BacteriaAlso known as anaerobes.
Bacteria that live and reproduce in an environment containing no "free" oxygen or DO (this type of environment is referred to as anoxic conditions). Anaerobic bacteria obtain their oxygen supply by breaking down chemical compounds which contain oxygen, such as sulfate.
|
AnaerobicA condition in which dissolved molecular oxygen is not present, however, some chemically bound oxygen may be present.

Aerobic BacteriaAlso called aerobes
Bacteria that must have molecular (dissolved) oxygen to survive. Bacteria that will live and reproduce only in an environment containing oxygen, which is available for their respiration (breathing), namely atmospheric oxygen or oxygen dissolved in water. Oxygen combined chemically, such as in water molecules (H2O), cannot be used for respiration by aerobic bacteria.
