Effects of different lignin-blocking additives on the glucose yields of PSA-Ba and DA-Ba substrates. The addition concentration of lignin-blocking additives, cellulase and β-glucosidase loadings in enzymatic buffer solution were 1.0 g/L, 5 FPU, and 10 CBU/g glucan, respectively. The pH value of enzymatic buffer solution was 5. LS, PVA, Tween, BSA, and PP refer to the lignosulfonate, poly(vinyl alcohol), Tween 20, bovine serum albumin, and peanut protein, respectively
