TL;DR: In this article, the authors reveal recombinant bacteria with improved alpha-phenylpyruvic acid transformation production efficiency, and belong to the field of biotechnology, achieving a yield of 3.9 g/L. According to the invention, the knockout of aspC, tyrB and ilvE genes from Escherichia coli is achieved successfully, so that the degradation of the product PPA by cells is blocked, and the yield of extracellularly transformed L-pylalanine is further improved.
