Comparison diol production (a) and growth (b) on complex and defined medium. E. coli W ΔldhA ΔadhE Δpta ΔfrdA 445_Ediss is compared in shake flasks with 10 g l−1 yeast extract or in defined medium (1- or 0.5-fold amino acid concentration and onefold vitamin concentrations). Light bars represent growth and production without the addition of acetate and dark bars with acetate. Mean values and standard deviations were calculated from biological triplicates
