Resveratrol is a well-known polyphenol present in red wine and exerts antioxidative and anti-carcinogenic effects on the human body. To produce resveratrol in a food-grade yeast, the 4-coumarate:coenzyme A ligase gene (4CL1) from Arabidopsis thaliana and stilbene synthase gene (STS) from Arachis hypogaea were cloned and transformed into Saccharomyces cerevisiae W303-1A. The resveratrol produced was unglycosylated and secreted into the culture medium. A batch culture with 15.3mg/l p-coumaric acid used as precursor resulted in the production of 3.1mg/l resveratrol with 14.4 mol% yield. Deletion of the putative phenyl acrylic acid decarboxylase gene (PAD1) did not enhance resveratrol production.
白藜芦醇是一种存在于红酒中的多酚,对人体具有抗氧化和抗癌作用。为了在食品级酵母中生产白藜芦醇,我们从拟南芥中克隆了 4-香豆酸:辅酶 A 连接酶基因(4CL1)和花生中的芪合酶基因(STS),并将其转化到酿酒酵母 W303-1A 中。所产生的白藜芦醇未经糖基化就分泌到培养基中。以 15.3mg/L 的对香豆酸作为前体进行分批培养,可得到 3.1mg/L 的白藜芦醇,产率为 14.4 摩尔%。删除推定的苯丙烯酸脱羧酶基因(PAD1)并没有提高白藜芦醇的产量。
