LACTOBACILLUS PARACASEI LA104 PRODUCING L-LACTIC AICD

摘要

PURPOSE: Lactobacillus paracasei LA104 which produces L-lactic acid(LA) is provided to produce a large amount of high purity L-lactic acid by 3-5 g/L of a yeast extract. CONSTITUTION: Lactobacillus paracasei LA104 is provided to produce L-lactic acid. The strain has resistance to stress conditions such as high temperature, high salinity, high lactic acid concentration, high glucose concentration, and low pH concentration. A method for producing L-lactic acid using the strain comprises: a step of injecting the strain, 70-80 g/L of Hydrodictyon reticulum algae, saccharifying enzyme, and 3-5 g/L of a yeast extract to a fermentation device; and a step of fermenting.
