Abstract
Official abstract text for this publication.
The present invention relates to a microorganism of the genus Escherichia in which L-tryptophan productivity is improved by inactivating phosphatase activity. Further, the present invention relates to a method for producing L-tryptophan using the microorganism of the genus Escherichia.
First claim
Opening claim text (preview).
The invention claimed is: 1. A modified microorganism of the genus Escherichia producing L-tryptophan, wherein the activity of phosphatase comprising the amino acid sequence of SEQ ID NO: 1 is inactivated. 2. The microorganism according to claim 1 , wherein the microorganism of the genus Escherichia is Escherichia coli. 3. A method for producing L-tryptophan, comprising: (i) capturing the microorganism of the genus Escherichia of claim 1 in a medium; and (ii) recovering L-tryptophan from the cultured microorganism and the medium. 4. A method for producing L-tryptophan, comprising: (i) capturing the microorganism of the genus Escherichia of claim 2 in a medium; and (ii) recovering L-tryptophan from the cultured microorganism and the medium.
