Turbidostat cultures of Clostridium acetobutylicum were analysed with respect to their fermentation products after steady states were obtained at various cell densities. It was found that at low densities the fermentation of glucose was essentially acidogenic in nature, whereas acetone and butanol w

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
## Normal amounts of acetone and butanol wcrc formed during the fermentation of glucose in a defined minimal medium in pH-regulated batch cultures (pH 5.0). No solventogenesis occurred during glucose-or ammonium-limited growth in a chemostat. Moreover, the capacity toproduce solvents appeared to
