✦ Synopsis

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 were the major end-products when the cultures were maintained at a high cell density.

## 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
