Zusammenfassung:	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 the 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. La présente invention concerne un micro-organisme recombiné pour la production de 2,3-butanediol, par lequel, dans un micro-organisme doté de la voie de biosynthèse du 2,3-butanediol, au moins un élément choisi dans le groupe constitué par une voie de conversion de l'acide glutamique en acide polyglutamique, une voie de conversion du saccharose en lévane, une voie de conversion du pyruvate en lactate et une voie de conversion du glycérophosphate en glycérol est inhibé. La présente invention concerne également un procédé pour produire du 2,3-butanediol en utilisant le micro-organisme recombiné pour produire du 2,3-butanediol. 본 발명은 2,3-부탄다이올 생합성 경로를 갖는 미생물에 있어서, 글루탐산을 폴리글루탐산으로 전환하는 경로, 슈크로즈를 레반으로 전환하는 경로, 피루브산을 젖산으로 전환하는 경로 및 글리세로포스페이트를 글리세롤로 전환하는 경로로 구성되는 군으로부터 선택되는 하나 이상이 억제된, 2,3-부탄다이올 생산용 재조합 미생물에 대한 것이다. 또한 본 발명은 상기 2,3-부탄다이올 생산용 재조합 미생물을 이용한 2,3-부탄다이올의 생산 방법에 대한 것이다.
