  • Publication number: 20190365640
    Abstract: Lactobacilus reuteri CH53 strain has high productivity of 1,3-propanediol from glycerol and uses thereof. It is confirmed that Lactobacilus reuteri CH53 strain is capable of converting at very high yield glycerol or crude glycerol to high-concentration 1,3-propanediol. Since Lactobacilus reuteri CH53 strain of the present invention capable of producing large amounts of 1,3-propanediol is one kind of lactic acid bacteria that are safe for humans (GRAS, Generally Recognized As Safe), when it is used for producing 1,3-propanediol from crude glycerol, it would be very advantageously used, unlike existing GMO strains, in related industries from the viewpoint of safety or environment and also providing an advantage of recycled use of resources.
