## 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
The effects of growing Clostridiurn acetobutylicurn NCIB 8052 in a chemostat under conditions of glucose, NH,', PO$-, Mg2+, and Fez+ limitation were examined. It was noted that limitation of any major nutrient resulted in the same fermentation pattern. Conditions where minor nutrient levels were red
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 concentrat
