Fermentative production of solvents (acetone, butanol, and ethanol) by Clostridium acetobutylicum is generally a biphasic process consisting of acidogenesis and solventogenesis. We report that the biphasic metabolism of C. acetobutylicum could be changed by oxidoreduction potential (ORP) regulation. When using air to control the ORP of the fermentation broth at −290 mV, an earlier initiation of solventogenesis was achieved. Solvent production reached 25.6 g l−1 (2.8 g acetone l−1, 16.8 g… CONTINUE READING
