  • RECOMBINANT MICROORGANISM FOR PRODUCING 2,3-BUTANEDIOL WITH REDUCED BY-PRODUCT PRODUCTION AND METHOD FOR PRODUCING 2,3-BUTANEDIOL BY USING SAME
    Publication number: 20240182931
    Abstract: The present invention relates to a recombinant microorganism for producing 2,3-butanediol, in which, in a microorganism having the 2,3-butanediol biosynthetic pathway, at least one selected from a group consisting of a pathway for converting glutamic acid into polyglutamic acid, a pathway for converting sucrose into levan, a pathway for converting pyruvate into lactate, and a pathway for converting glycerophosphate into glycerol is inhibited. The present invention also relates to a method for producing 2,3-butanediol by using the recombinant microorganism for producing 2,3-butanediol.
