Fermentation (ferment = rearrange)A bi Di ti – Anaerobic Digestion –

A set of anaerobic reactions in which pyruvate A set of anaerobic reactions in which pyruvate generated by glycolysis is modified to ethanol, lactate, or some other organic end product. A l i f ti hi h t l d A complex series of reaction which are catalyzed by a consortium of microorganism and accomplish the conversion of organic compound to the t i l d tsterminal productsThe sum of reactions which converts a wide array of substrate materials having carbon at array of substrate materials having carbon at various oxidation/reduction to one carbon molecules in the most oxidized (CO2) and most reduced statereduced state
