✦ Synopsis
Electrodialysis
culture of Clostridium thermoaceticum increased the yield of acetate by its continuous removal. In normal batch cultures without pH control the yield was 4.2 g acetic acid/800 ml, while in pH-controlled culture it was 16.8 g/800 ml. Although electrodialysis cultures gave almost the same yield (15.4 g/800 ml) as that in pH-controlled cultures, sparging CO, into the broth in electrodialysis culture increased the amount of acetic acid to 22.3 g/SO0 ml. CO, sparging into normal cultures with or without pH control did not significantly increase the amount of acetate produced but yields, in terms of amounts of glucose consumed, were higher than without sparging. The theoretical yield was almost obtained in pHcontrolled, electrodialysis cultures with CO, sparging.
