Zusammenfassung:The present application relates to a microorganism of the genus Escherichia producing L-tryptophan and, more specifically, to a microorganism of the genus Escherichia with improved activity of producing L-tryptophan by weakening or inactivating the activity of endogenous 6-phosphogluconate dehydratase and 2-keto-3-deoxy-6-phosphogluconate aldolase. Additionally, the present application relates to a method for producing L-tryptophan using the microorganism of the genus Escherichia.
