Beschreibung
Zusammenfassung:The present invention provides a method for producing L-amino acids such as L-amino acids belonging to the glutamate family by fermentation using a bacterium of the family Enterobacteriaceae, particularly a bacterium belonging to the genus Escherichia, which has been modified to attenuate expression of at least one of the genes from the znuACB gene cluster. La présente invention porte sur un procédé de production d'acides L-aminés, tels que les acides L-aminés appartenant à la famille du glutamate, par une fermentation utilisant une bactérie de la famille des Enterobacteriaceae, en particulier une bactérie appartenant au genre Escherichia, qui a été modifiée pour atténuer l'expression d'au moins l'un des gènes de la batterie de gènes znuACB.
