Objectives
1 To construct the strains which are suitable for industrial production of phenylalanine at low cost, which in turn reduces the expense of aspartame synthesis.
2 To establish the technical platform of E. coli anabolic gene regulation in order to set up the basis for transforming metabolic pathway of aromatic amino acid in E. coli in the future. Not only it can be used to enhance the production capacity and rate of aromatic amino acid, such as phenylalanine, tryptophan, and tyr...
