Depicting the highest yields obtained for the three OrganoCat products over all conditions and for ten different lignocellulosic materials (for full data set, see Additional file 1: Table S1). Yields are expressed in percentage of initial dried material, as mean ± standard deviation; n = 3
^aPercentage by weight in relation to the initial biomass
^bPercentage by weight in relation to pulp
^cTemperature dependence is defined as slope of the linear regression between the different glucose release values from enzymatic hydrolysis of pulps after 72 h for FDCA pretreatment at 140, 150, and 160 °C
