Lactic acid - Preparation of enzymatic method

Chlorine acid enzymatic conversion: the use of the purified L-2-halo acid Calcium lactate and DL-2-halo acid degreasing Halogen enzyme acts on the substrate, respectively, L-2-chloro-propionic acid and DL-2-chloro-propionic acid, L-lactic acid was off or Stewed D-lactic acid. L-2-halo acid dehalogenase catalyzed L-2-chloropropionic acid, and DL-2-halo acid buffered lactic acid Catalytic both L-2-chloropropionic acid, but also the catalytic L-2-chloropropionic acid to form the corresponding optically active, catalytic Simultaneous transformation configuration. Enzymatic conversion of pyruvate: lactate dehydrogenase activity was the highest from mixed DSM20196 disorder Lactobacillus cells obtained in D-lactic acid dehydrogenase, a non-optically active pyruvate Substrate D-lactic acid can be obtained.
