Fig. 5From: Efficient biosynthesis of pinosylvin from lignin-derived cinnamic acid by metabolic engineering of Escherichia coliPinosylvin production by recombinant E. coli harbouring different modules. The strains were cultivated at 30 °C for 48 h in YM9 medium, and 90 mg/L trans-cinnamic acid was added. The data represent the means of two replicates, and error bars represent standard deviations. “*” indicates p < 0.05, “**” indicates p < 0.01Back to article page
