Fig. 5From: Effective isopropanol–butanol (IB) fermentation with high butanol content using a newly isolated Clostridium sp. A1424Isopropanol–butanol fermentation analysis with regard to NAD(P)H levels. A subscript “C” means ‘per C mole of consumed substrate.’ a Fraction of NAD(P)H from Fd per required NAD(P)H for products, b alcohol (IB, BuOH, and IPA) production per C mole of consumed substrate, c non-alcohol (ACT, AA, and BA) production per C mole of consumed substrate, d NAD(P)H-generating metabolites per C mole ([IPA + ACT +AA]C) and the other metabolites per C mole ([BuOH + BA]C).
