Digestion of materials in the absence of oxygen. See: anaerobic respiration.

The complex process by which organic matter is decomposed by anaerobic bacteria. The decomposition process produces a gaseous byproduct often called "biogas" primarily composed of methane, carbon dioxide, and hydrogen sulfide.

A biochemical process by which organic matter is decomposed by bacteria in the absence of oxygen, producing methane and other byproducts.

Degradation of organic matter by microbes in the absence of oxygen to produce methane and carbon dioxide.
