Expression of Codon-Optimized Plant Glycosyltransferase UGT72B14 in Escherichia coli Enhances Salidroside Production

Figure 6

Result of salidroside production in vivo. (a) Batch cultivation. (b) Fed-batch cultivation. Sal-opt and Sal-wt refer to salidroside synthesized by strains harbouring codon-optimized and wild-type UGT72B14 plasmids, respectively. Tyr-opt and Tyr-wt refer to tyrosol concentration in the culturing broth of strains harbouring codon-optimized and wild-type UGT72B14 plasmids, respectively. Black arrows indicate substrate additions, and red arrows indicate substrate feeding during cultivation. Samples were tested three times. Data are presented as mean, and error bar represents the SD.
