Small-scale ionic liquid (IL) pretreatment, enzymatic hydrolysis, and α-bisabolene production using WT and QsuB poplar biomass. The amount of (A) fermentable sugars and (B) aromatics measured in hydrolysates after IL pretreatment (105 °C for 1 h) and enzymatic hydrolysis are shown. DHB: 3,4-dihydroxybenzoate; 4-HBA: 4-hydroxybenzoate; VA: vanillate. (C) α-Bisabolene titers obtained after fermentation of hydrolysates using the R. toruloides GB2 strain. Grey diamonds indicate optical densities of the cultures at the end of the experiment. Error bars represent the standard error of three technical replicates conducted on a biomass pool from eight plants. Asterisks indicate significant differences from the WT hydrolysates using the unpaired Student's t-test (*p < 0.05; **p < 0.01)
