Disclosed are Escherichia coli that improve or resolve the diauxy problems that were a flaw in the KO11 strain of recombinant ethanol-producing Escherichia coli, a method for manufacturing ethanol using the same, and an ethanol-containing solution produced thereby. Disclosed are recombinant Escherichia coli obtained by destroying or eliminating the ptsG gene of the KO11 strain of Escherichia coli. L'invention concerne des Escherichia coli qui améliorent ou résolvent les problèmes de diauxie qui étaient un inconvénient de la souche KO11 d'Escherichia coli recombinante produisant de l'éthanol, un procédé de fabrication d'éthanol l'utilisant et une solution contenant de l'éthanol ainsi produite. L'invention concerne des Escherichia coli recombinantes qui sont une modification de la souche KO11 d'Escherichia coli dans laquelle le gène ptsG a été détruit ou endommagé.
