Summary
Carbon monoxide sparged in batch fermentations ofC. acetobutylicum inhibits the production of H2 by the hydrogenase and enhances the production of solvents by making available larger amounts of NAD(P)H2 to the cells. CO also inhibits biomass growth and acid formation. Its effect is most pronounced under fermentation conditions of excess carbon- and nitrogen-source supply.
