heterofermenters. e final products of strains from both groups con-
tain lactic acid though two different pathways of lactic acid produc-
tion. Homolactic and heterolactic fermentations by lactic acid bacteria
are demonstrated below. Homofermenters produce mainly lactic acid,
via the glycolytic ( Embden- Meyerhof) pathway. Heterofermenters
produce lactic acid plus appreciable amount of ethanol, acetate and
carbon dioxide, via the 6-phosphoglucanate/ phosphoketolase path-
way (Axelsson, 1998). Homolactic fermentation converts one mole of
glucose into two moles of lactic acid, whereas the heterolactic fermen-
tation converts ...
