2.5-L bioreactor cultivations VI and VII with a pH-coupled feed and 90 g/L CaCO3. The pH was controlled with 10 M acetic acid (VI), or 10 M acetic acid and 5 M NaOH (VII). Fermentations were performed at 32 °C with a stirrer velocity of 600 rpm and an aeration rate of 0.5 vvm. Datapoints represent means ± standard deviation, n = 2 (VI) or n = 3 (VII)
