Abstract: PURPOSE: A method for preparing GABA from mono sodium glutamate using a Lactobacillus strain or recombinant Lactobacillus strain is provided to ensure high productivity. CONSTITUTION: A method for preparing GABA by Lactobacillus strain comprises: a step of culturing the strain in a medium containing MSG(mono sodium glutamate) and glycine, chloroform, or EDTA for 48-96 hours; and a step of collecting GABA from the culture liquid. The strain is Lactobacillus brevis.

Abstract: PURPOSE: A method for producing butnaol of high productivity using a strain is provided to be used in industrial technology. CONSTITUTION: A mutant Clostridium beijerinckii CBE-2-68 which produces butanol with high yield is deposited in the deposit number KCTC11606BP. A method for producing a large amount of butanol comprises: a step of culturing the Clostridium beijerinckii CBE-2-68 strain; a step of centrifuging the culture liquid to collect supernatant; and a step of purifying butanol.
