In this study, a biosynthetic pathway for the production of anisyl alcohol from simple carbon sources was established in engineered Escherichia coli MG1655. Anisyl alcohol production was further increased to 355 mg/L by increasing the availability of erythrose-4-phosphate and phosphoenolpyruvate. Additionally, anisyl acetate was produced by overexpressing alcohol acetyltransferase ATF1 for the acetylation of anisyl alcohol. This is the first report on the biosynthesis of anisyl alcohol and anisyl acetate directly from a renewable carbon source.
Anisyl alcohol and its ester anisyl acetate are both important fragrance compounds and have a wide range of applications in the cosmetics, perfumery, and food industries. The currently commercially available anisyl alcohol and anisyl acetate are based on chemical synthesis. However, consumers increasingly prefer natural fragrance compounds. Therefore, it is of great significance to construct microbial cell factories to produce anisyl alcohol and anisyl acetate. In this study, we first established a biosynthetic pathway in engineered Escherichia coli MG1655 for the production of anisyl alcohol from simple carbon sources. We further increased the anisyl alcohol production to 355 mg/L by the increasing availability of erythrose-4-phosphate and phosphoenolpyruvate. Finally, we further demonstrated the production of anisyl acetate by overexpressing alcohol acetyltransferase ATF1 for the subsequent acetylation of anisyl alcohol to produce anisyl acetate. To our knowledge, this is the first report on the biosynthesis of anisyl alcohol and anisyl acetate directly from a renewable carbon source.
