Cell growth, ABE production and furfural reduction by C. beijerinckii 8052 culture challenged with furfural (3 g/L) at the solventogenic phase. Fermentation was monitored for 4 h post-furfural challenge and samples were collected every hour for analyses. Quantified parameters include cell growth (A), acetone (B), butanol (C), ethanol (D), acetic acid (E), butyric acid (F), and residual furfural (G).
