Fermentation of Acetate
Acetic acid can also undergo a dismutation reaction to produce methane and carbon dioxide:
- CH3COO– + H+ → CH4 + CO2 ΔG° = -36 kJ/mol
This disproportionation reaction is catalysed by methanogen archaea in their fermentative metabolism. One electron is transferred from the carbonyl function (e– donor) of the carboxylic group to the methyl group (e– acceptor) of acetic acid to respectively produce CO2 and methane gas.

Famous quotes containing the words fermentation of and/or fermentation:
“A tree is made to live in peace in the color of day and in friendship with the sun, the wind and the rain. Its roots plunge in the fat fermentation of the soil, sucking in its elemental humors, its fortifying juices. Trees always seem lost in a great tranquil dream. The dark rising sap makes them groan in the warm afternoons. A tree is a living being that knows the course of the clouds and presses the storms because it is full of birds’ nests.”
—Jacques Roumain (1907–1945)
“Two principles, according to the Settembrinian cosmogony, were in perpetual conflict for possession of the world: force and justice, tyranny and freedom, superstition and knowledge; the law of permanence and the law of change, of ceaseless fermentation issuing in progress. One might call the first the Asiatic, the second the European principle.”
—Thomas Mann (1875–1955)
