Synthetic 1-butanol pathway expressed in the mixed-acid fermentation mutant. The mixed-acid mutant strain (ΔldhA ΔfrdBC ΔadhE Δpta) relies on the CoA-dependent 1-butanol pathway to recycle the NADH generated in glycolysis and to restore anaerobic growth. Different microbial sources of the 1-butanol pathway enzymes are shown in the parenthesis: EC, Escherichia coli; CA, Clostridium acetobutylicum; TD, Treponema denticola; CB, Candida boidinii
