Fig. 5

Estimated model parameters for fermentation experiments with varying fractions of unremoved inhibitory compounds resulting from the pyrolytic oils, (ac). d Ethanol yields from each of the fermentation experiments. The colors represent a specific detoxification route, symbols shown in black represent samples from detoxification step (W-H), blue represents W-EAc-H while green represents W-H-EAc. The X-axis shows the relative amount of inhibitory compounds (IV/G)/µL in the total volume of the micro-fermentations. AACC stands for acetic acid corn cobs extracts, ANCC nitric acid corn cobs extracts, AASG for acetic acid switchgrass and NASG for nitric acid switchgrass. The solid lines represent linear regression analysis of all data with IV/G > 200. The data points in the circles were excluded from the regression analysis
