General description

L-(+)-Lactic acid is the only naturally occurring lactic acid in humans and mammals. Commercially, few bacteria like Lactobacillus casei, L. delbrueckii, Streptococcus lactis produces L-Lactic acid by fermentation process. Lactic acid activates hydroxycarboxylic acid receptor, G-protein coupled receptor 81 (GPR81).

Application

Lactic acid has been used:
  • as a component in substrate solution II for lactate dehydrogenase reaction
  • as an additive in storage solution A
  • as a supplement in the artificial gastric juice preparation for evaluation of degree of resistance Lactobacillus to the gastric stresses

Biochem/physiol Actions

L-(+)-Lactic acid is used as a substrate for lactic acid dehydrogenase and lactate oxidase.
