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 production and to a method for producing L-tryptophan using same. More particularly, the present invention relates to an Escherichia coli mutant strain in which repression and attenuator regulation of the tryptophan operon are released and accumulation of anthranilate is reduced to thus enhance L-tryptophan production. The present invention also relates to a method for producing L-tryptophan using the Escherichia coli mutant strain.
