- Resveratrol (3,5,4 '-trihydroxy-trans-stilbene) is a phenolic compound widely used in pharmaceutics and nutraceutics. Although resveratrol is produced by some plant species, including grapes, peanuts, and berries, the content of resveratrol and its derivatives are very low. Therefore, an alternative biosynthetic method using microorganisms, such as Escherichia coli, has been developed over the past two decades. In the present study, a resveratrol-over-producing E. coli strain was developed using three strategies. First, we increased the synthesis of p-coumaric acid, a precursor of resveratrol, by manipulating genes in the shikimate pathway of E. coli. Second, three genes involved in resveratrol biosynthesis, such as tyrosine ammonia lyase (TAL), 4-coumaroyl CoA ligase (4CL), and stilbene synthase (STS), were cloned from diverse sources, such as plants and microorganisms, and the best combination was selected to maximize resveratrol production in E. coli. Finally, culture conditions, such as cell concentration, culture temperature, and carbon sources, were established for optimal resveratrol production. Through these strategies, approximately 80.4 mg/L of resveratrol was biosynthesized after 48 h of culture using glycerol as a carbon source.
