Biological Alternative to Create Aromatic Esters Using Engineered Microorganisms as the Biocatalyst

Description
Four enzymes, ATF1, ATF2, ATF, and CAT, were screened to determine which would be most effective at catalyzing the formation of aromatic esters. The CAT enzyme successfully catalyzed the reaction to produce 2-phenethyl acetate using 20x more lysate to improve the probability of enzyme presence in the lysate. The CAT…

Four enzymes, ATF1, ATF2, ATF, and CAT, were screened to determine which would be most effective at catalyzing the formation of aromatic esters. The CAT enzyme successfully catalyzed the reaction to produce 2-phenethyl acetate using 20x more lysate to improve the probability of enzyme presence in the lysate. The CAT enzyme was able to catalyze the reaction producing concentrations that increased by 62% every 12 hours. Enzymatic activity resulted in the production of 2.15 mg/L of 2-phenethyl acetate at 12 hours, 5.62 mg/L of 2-phenethyl acetate at 24 hours, and 15.12 mg/L of 2-phenethyl acetate at 48 hours.
