Fig. 4From: Metabolic engineering of Escherichia coli into a versatile glycosylation platform: production of bio-active quercetin glycosidesComparison of the specific productivity qp of the sGAL (a hyperoside formation) and sRHA (b quercitrin formation) strains. Strains were grown on minimal medium containing 0.15 g/L (gray bars) and 1.5 g/L (black bars) quercetin. Error bars represent standard deviationsBack to article page
