Salidroside production in engineered S. cerevisiae. S. cerevisiae BG4 strains expressing codon-optimized genes encoding the three indicated uridine-diphosphate–dependent glycosyltransferases were cultivated as described in the “Material and Methods” section. The final concentrations of the aromatic amino acids l-Ph and l-Tyr and of tyrosol and salidroside in the culture supernatant obtained after 72 h of cultivation are shown. Data represent the mean ± se of at three biological replicates.
