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 disrupt putrescine degradation pathway by, for example, inactivation of one gene or several genes from the puuADRCBE gene cluster. La présente invention concerne un procédé de production d'acides aminés L tels que les acides aminés L appartenant à la famille du glutamate par fermentation au moyen d'une bactérie de la famille Enterobacteriaceae, en particulier une bactérie appartenant au genre Escherichia, qui a été modifiée pour perturber la voie de dégradation de la putrescine par, par exemple, inactivation d'un gène ou plusieurs gènes du cluster de gènes puuADRCBE.
