A1424Effect of the mixture of glucose and crude glycerol on isopropanol–butanol fermentation. a cell growth, glucose, glycerol, and pH, b metabolite production, c carbon recovery to butanol and isopropanol. DCW dry cell weight, BuOH butanol, IPA isopropanol, ACT acetone, B + I butanol + isopropanol, AA acetic acid, BA butyric acid. The fermentation was performed on serum bottles without pH control.
