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 the putrescine degradation pathway by, for example, inactivation of one gene or several genes from the puuADRCBE gene cluster.
