An object of the present invention is to provide a method for producing 2,3-butanediol (BDOH) and / or acetoin using E. coli having a high production concentration. [MEANS FOR SOLVING PROBLEMS] A gene encoding acetolactate synthase and a gene encoding acetolactate decarboxylase have been introduced into Escherichia coli, or a butanediol dehydrogenase (butanediol dehydrogenase). A genetically modified Escherichia coli capable of producing acetoin and / or 2,3-butanediol, in which a gene encoding is introduced. [Selection figure] None |
