Lactic acid is a very important chemical having various applications in the field of pharmaceutical, cosmetics, textile, leather and food industries. Pure sources of the D(-) and L(+) enantiomers can be blended to vary the physical properties and biodegradation rates of polylactides. Lactic acid is able to be produced by chemical synthesis or bacterial fermentation, but none of chemical production routes shows technical and economical viability. Significant advantage of biotechnological production of lactic acid by fermentation over chemical synthesis is that can sue cheap raw materials. In this presentation, we developed several metabollically engineered strain for the production of pure L- or Denantiomer and will show the production of lactic acid using these lactic acid bacteria.. Detailed results will be presented.
