Effects of modified lignins on glucose yield in enzyme saccharification of Avicel. a Enzymatic saccharification of Avicel with lignin loading of 4 g/L; b enzymatic saccatification of Avicel with mixture of AL (2 g/L) and modified lignins (2 g/L). Enzymatic saccharification was conducted at 50 °C and 150 rpm in the 0.05 M sodium acetate buffer (pH 4.8) for 72 h, with the cellulase (UTA-8) loading of 10 FPU/g glucan
