Eriodictyol production, intermediate metabolites, and CoA-thioesters accumulated in engineered E. coli strains at different postinduction phases. ■, BF1; ●, BF2; ▲, BMF1; ▼, BMF2. The strains were induced under their optimal culture conditions (30°C for BF1 and BF2; 25°C for BMF1 and BMF2). Data are averages of results for three biological replicates. Error bars represent standard deviations from the means. DCW, dry weight of cells.
