Tyrosol production of plasmid-based engineered strains. Fermentation profiles of tyrosol production of strain PGs harboring pCF1s-TDC-TYO (A) or pCF1s-TYO-TDC (B). Each of the transformants was cultured up to 72 h at 30 °C. Phe, black squares; Tyr, blue squares; tyramine, orange triangles; tyrosol, red triangles; OD, white circles. Data are presented as mean values with standard deviations for three independent experiments. Symbols without an error bar indicate that they are larger than the size of the error bar
