MICROORGANISMS OF ESCHERICHIA COLI HAVING ENHANCED L-TRYPTOPHAN PRODUCTION AND METHOD FOR PRODUCING L-TRYPTOPHAN USING SAME

摘要

The present invention relates to microorganisms of Escherichia coli having enhanced L-tryptophan productivity and to a method for producing L-tryptophan using the same. More particularly, the present invention relates to an Escherichia coli variant in which repression and attenuation control of the tryptophan operon is released and accumulation of anthranilate is reduced and thereby enhancing L-tryptophan productivity. The present invention also relates to a method for producing L-tryptophan using the Escherichia coli variant.
