Added ethanol tSSF. Experimental data (points) and model results (lines) from 20 g/L initial Avicel concentration tSSF (4 FPU/g cellulose) supplemented with initial ethanol at concentration of 1.09 (black, solid), 16.82 (red, dashed) and 32.17 (blue dash-dot) g/L. The model over predicts conversion of 20 g/L Avicel in the presence of high concentrations of added ethanol. Error bars indicate standard deviation on the conversion measurement.
