fermentation
fermentation A form of
anaerobic respiration occurring in certain microorganisms, e.g. yeasts.
Alcoholic fermentation comprises a series of biochemical reactions by which pyruvate (the end product of
glycolysis) is converted to ethanol and carbon dioxide. It is the basis of the baking and
brewing industries (see
baker's yeast). In
lactic-acid fermentation, which occurs in many microorganisms and (when sugar is in short supply) in animal cells, the end product is lactic acid. Microorganisms display a range of fermentations, producing not only ethanol or lactic acid, but other products, such as propionic and butyric acids, acetate, and methane.
