The kinetics in fed-batch cultures of acetone butanol fermentation by Clostridiurn acetobutylicurn is compared on glucose, xylose, and mixtures of both sugars. The final conversion yield of sugars into solvents always increases with the sugar feeding rate. At low feeding rates, the sugar concentrati

β¦ Synopsis
Clostridium acetobutylicum was grown in fed-batch cultures at different feeding rates of glucose. The sugar converted to butanol and acetone increased with increasing the glucose flow, on the contrary the conversion to butyric acid was highest st slow glucose feeding rate. The acetic acid concentration was constant at the different flows of glucose. The solventogenesis was not inhibited at high flow of sugar.

## Abstract **BACKGROUND:** Owing to the rapid depletion of petroleum fuel, the production of butanol through biological routes has attracted increasing attention. However, low butanol productivity severely impedes its potential industrial production. It is known that the immobilization of whole ce
