We use renewable resources corn, potato raw material, prepared by fermentation using microorganisms of optically pure L-lactic acid or D-lactic acid. And L-lactic acid than the buffered lactic acid can be completely absorbed by the body, without any side effects.
Production of L-lactic acid, so we adopt a common foreign Rhizopus oryzae NAF-032.
⑴ preparation Rhizopus oryzae spores;
⑵ will Rhizopus oryzae spores prepared milk spore suspension;
⑶ milk will Rhizopus oryzae spores suspension immobilized carrier is fixed to be immobilized Rhizopus oryzae seed;
⑷ The immobilized Rhizopus oryzae fermentation medium inoculated seeds immobilization fermentation.
This method bred Ethyl lactate strains of rice and Rhizopus cotton carrier fixed to the immobilized Rhizopus oryzae get seeds in a suitable fermentation conditions immobilized fermentation, potato starch conversion rate, high biomass fermentation products, L-lactic acid yield, low cost, simple procedure, easy to control, etc.
