What You Need to Know
During fermentation, lactic acid bacteria metabolize glucose and fructose to produce lactic acid, lowering the pH to 4.0–4.5 and creating an environment hostile to spoilage organisms. The process also generates other organic acids such as acetate and propionate, and bacteriocins like nisin, which further inhibit pathogens.
The Science
Primary Reaction
Fermentation of fermentable sugars to lactic acid via homo- and heterofermentative pathways
