This article reviews the metabolism of pyruvate and lactate by lactic acid bacteria (LAB) involved in food and beverage fermentations with an emphasis on practical implications. First, the formation of pyruvate and lactate from a range of substrates, including carbohydrates, organic acids and amino acids, is briefly described. The catabolism of pyruvate and lactate by LAB is then reviewed. This is followed by a discussion of lactate degradation and racemisation by LAB from specific fermented foods and beverages. Finally, the impact of environmental factors and metabolic engineering on pyruvate and lactate metabolism by LAB is evaluated with regard to practical significance.
