Fig. 2From: Effective isopropanol–butanol (IB) fermentation with high butanol content using a newly isolated Clostridium sp. A1424Isopropanol–butanol fermentation with 21.6 g/L initial glucose concentration (a, b), 41.0 g/L initial glucose concentration (c, d), and 58.9 g/L initial glucose concentration (e, f). 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.
