Main parameters of the cultures and characteristics of plasmid DNA production in the different media. a Specific growth rate, b acetate concentration in the broth, c final pH of the broth, d pDNA concentration, e pDNA yield on biomass (Y pDNA/OD ), f supercoiled pDNA fraction. All cultures were carried out in duplicate. Error bars show the experimental error between duplicates. Black bars 5.4-kbp plasmid, open bars 6.0-kbp plasmid, gray-shaded bars 7.8-kbp plasmid
