Fermentation is anaerobic conversion of organic materials in the absence of inorganic electron acceptors such as sulfate, nitrate, or oxygen. ... However, the most abundant substrates for fermentation, and a primary route for carbon flux, are monosaccharides and amino acids.Fermentation is a metabolic process that converts sugar to acids, gases, and/or alcohol. It occurs in yeast and bacteria, but also in oxygen-starved muscle cells, as in the case of lactic acid fermentation.
