was autoclaved in the bioreactor and medium supplements, kanamycin (30 mg/L) and glucose(20 g/L) were added separately. The reactor was then inoculatedwith the volume of the prepared inoculum required to set the ini-tial OD600to 0.1. The dissolved oxygen set-point was controlled at30% using an agitation cascade (250–800 rpm) and air was providedat a flow rate of 1 vvm. The pH was controlled at 7.10 using 1 MNaOH and 1 M H2SO4. Antifoam was manually added as required.Samples were taken periodically from the bioreactor to quantifybiomass, glucose, acetate and pDNA.
