The effect of the component concentrations of a synthetic medium on acetone and butanol fermentation by Clostridium acetobutylicum ATCC 824 was investigated. Cell growth was dependent on the presence…

WhenClostridium acetobutylicum was grown in batch culture under iron limitation (0.2 mg·l−1) at a pH of 4.8, glucose was fermented, to butanol as the major fermentation end product, and small…

Clostridium acetobutylicum exhibited diauxie growth in the presence of mixtures of glucose and xylose, and butanol was shown to be a potent inhibitor of the growth of the organism and of the rate of sugar uptake as well as of sugar incorporation into cell materials.

Only the first phase of the acetone butanol fermentation (acid formation) was observed in the coculture of a mesophilic cellulolytic Clostridium and Clostridgeium acetobutylicum.

The third series of experiments showed that gases produced by the bacteria have a high toxic effect, comparable to that of 5 g l-1 of acid.
Acetone-butanol production from pentoses by Clostridium acetobutylicum
Clostridium acetobutylicum fermented glucose, arabinose, and xylose with a conversion of carbon source into solvents of 32, 29, and 28% respectively, with growth yields similar on the three sugars, but glucose orArabinose were consumed in preference to xylOSE and with faster growth.
Optimum reaction conditions for human lactate dehydrogenase isoenzymes as they affect total lactate dehydrogenase activity.
Calculation showed that both methods, P → L and L → P, were essentially equivalent, and this equivalency was verified by a comparative study of the two methods on human serum samples.
