A process of breakdown of organic molecules to simpler inorganic constituents, that occurs in the absence of oxygen.
The natural breakdown of organic matter requiring water but not oxygen.
Decomposition of cellulose and proteins occurring in the absence of oxygen, such as in landfill waste, producing methane and carbon dioxide. Anaerobic bioreactors increase the rate of methane generation, which can then be collected and used for energy recovery.
The breakdown of a molecule into simpler molecules or atoms by microorganisms in the absence of oxygen. Includes anaerobic digestion and anaerobic fermentation. The primary product of anaerobic decomposition is methane (CH4), a powerful greenhouse gas.
Reduction of the net energy level and change in chemical composition of organic matter caused by microorganisms in an oxygen-free environment.
Bacterial decomposition via biochemical pathways which do not require oxygen.
Decomposition of organic wastes occurring in the absence of oxygen, by bacteria which breathe an inorganic oxidant. Causes production and release of methane gas.
The breakdown of molecules into simpler molecules or atoms by microorganisms that can survive in the partial or complete absence of oxygen.
