  • Improving performance of a gas stripping-based recovery system to remove butanol from Clostridium beijerinckii fermentation

    The effect of factors such as gas recycle rate, bubble size, presence of acetone, and ethanol in the solution/broth were investigated in order to remove butanol from model solution or fermentation broth (also called acetone butanol ethanol or ABE or solvents). Butanol (8 g L–1, model solution, Fig. 2) stripping rate was found to be proportional to the gas recycle rate. In the bubble size range ...
