Salidroside is an important plant-derived aromatic compound with diverse biological properties. Because of inadequate natural resources, the supply of salidroside is currently limited. In this work, we engineered the production of salidroside in yeast. First, the aromatic aldehyde synthase (AAS) from Petroselinum crispum was overexpressed in Saccharomyces cerevisiae when combined with endogenous Ehrlich pathway to produce tyrosol from tyrosine. Glucosyltransferases from different resources were tested for ideal production of salidroside in the yeast. Metabolic flux was enhanced toward tyrosine biosynthesis by overexpressing pathway genes and eliminating feedback inhibition. The pathway genes were integrated into yeast chromosome, leading to a recombinant strain that produced 239.5 mg/L salidroside and 965.4 mg/L tyrosol. The production of salidroside and tyrosol reached up to 732.5 and 1394.6 mg/L, respectively, by fed-batch fermentation. Our work provides an alternative way for industrial large-scale production of salidroside and tyrosol from S. cerevisiae.
