Clostridium acetobutylicum cells were collected from chemostats which were run at pH 4.3 or 6.0 and which produced either acetone-butanol or acetate-butyrate; they were used to determine the level of enzymes involved either in solvent or in acid formation. The highest activity of phosphotransacetyla
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
