General Information

General Information	Comment	Organism
metabolism	lactic acid bacteria produce lactate, acetate, ethanol and carbon dioxide using the phosphoketolase pathway. When fructose is present, the redox balance can be maintained by the production of mannitol, which enables the formation of acetate instead of ethanol. The phosphoketolase has a lower energy yield in the form of ATP compared to that of the Embden-Meyerhof pathway (2 ATP for the Embden-Meyerhof pathway vs. only 1 for the phosphoketolase pathway) but it is used by lactic acid bacteria to ferment pentoses	Limosilactobacillus reuteri
