Abstract:
1. A method for producing an L-amino acid comprising culturing a microorganism having an ability to produce an L-amino acid in a medium to produce and accumulate the L-amino acid in the medium and collecting the L-amino acid from the medium, wherein the microorganism is a Gram-negative bacterium having the Entner-Doudoroff pathway and which has been modified so that 6-phosphogluconate dehydratase activity or 2-keto-3-deoxy-6-phosphogluconate aldolase activity, or activities of the both are enhanced, and the L-amino acid is selected from L-amino acids produced by a biosynthetic pathway utilizing pyruvic acid as an intermediate, wherein the 6-phosphogluconate dehydratase is encoded by edd gene and the 2-keto-3-deoxy-6-phosphogluconate aldolase is encoded by eda gene.
