Figure 5From: Synthetic sugar cassettes for the efficient production of flavonol glycosides in Escherichia coli The scale-up production of fisetin glycosides in 3 L fermentation at different time intervals. a Production profile of fisetin 3-O-glucoside by strain S4. b Production profile of fisetin 3-O-rhamnoside by strain S9. 0.35 mM fisetin dissolve in DMSO was successively added three times in both 3-L fermentation systems.Back to article page
