BUCT hopes to use 2-PE as an example to give E. coli Nissle 1917 the ability to sweetener hair in addition to improving scalp microecology. We use the natural phenylalanine synthesis pathway of E. coli to synthesize 2-PE. aroG was used to enhance the accumulation of a key intermediate, DAHP. aroG, as a metabolic pathway gene that has attracted much attention for many years, has always been a worthy object of study. We believe that its feedback inhibition may affect the synthesis of 2-phenylethyl alcohol. We use this Mutant Feedback-Resistant Version of aroG for to resisting feedback inhibition and improving enzyme activity. This is the composite of our Improvement of Standard Biological Parts. Our team successfully constructed a pathway for the synthesis of 2-phenylethanol in Escherichia coli. When cultured for 60 hours, the maximum concentration of 2-phenylethanol was 67.16mg/L.After 60 hours,the concentration of 2-phenylethanol decreases because of toxicity of 2-PE accumulated in E. coli and metabolism.
