    摘要： A method for producing an L-amino acid which comprisese culturing a bacterium belonging to the family Enterobacteriaceae and having an L-amino acid producing ability in a medium to produce and accumulate an L-amino acid in the medium and collecting the L-amino acid from the medium, wherein the bacterium has been modified so that activity or activities of one or two or more kinds of enzymes of the arginine succinyltransferase pathway, such as arginine succinyltransferase, succinylarginine dihydrolase, succinylornithine aminotransferase, succinylglutamate-semialdehyde dehydrogenase and succinylglutamate desuccinylase, is/are decreased.
