Microorganism of genus Escherichia having productivity of L-tryptophan intensified, and method for the production of L-tryptophan using the

摘要

Abstract 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.Nhancing L - tryptophan productivity. The present invention also relates to a method for producing L - tryptophan using the Escherichia coli variant.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * the translation of the summary summary invention patent: "microorganism of genus Escherichia having productivity of L-tryptophan intensified, and method for the production of L - CaIptofano using it. The present invention relates to microorganisms Escherichia coli having productivity of L-tryptophan intensified and a method for the production of L-tryptophan using them.More particularly,The present invention relates to a variant of Escherichia coli in the control of repression and attenuation of the opu00e9ron tryptophan is released and the accumulation of anthranilate is reduced.Thereby enhancing the productivity of L-tryptophan. The present invention also refers to a method for the production of L-tryptophan using the variant of Escherichia coli.21761800v1 1 / 1 21761800v1
