Minimum ethanol selling price (MESP), with off-site MESP as a function of enzyme price. Carbon source A: pretreated liquid fraction, B: pretreated liquid fraction and molasses; +: 1.5-fold specific activity; off-site: reference case with purchased enzyme preparation. The enzyme dosage of simultaneous saccharification and fermentation was 10 FPU g−1 water-insoluble solids. The price of enzyme per MFPU can be converted to price per kg of enzyme preparation by multiplying it by a factor of 0.194
