Free cellulase concentration in the hydrolyzate supernatant as a function of total lignin concentration. Data for free CBH I (blue squares), CBH II (green triangles), and EG I (red circles) after 48-h saccharification of Avicel (0 g/L lignin), IL-CS (0.58 g/L lignin), AFEX-CS (3.18 g/L lignin), and DA-CS (5.43 g/L lignin) at 50°C are reported here. All assays were carried out in triplicate with mean values shown here. Standard deviations in all cases were less than 5%.
