Figure 5: Simulation results considering oligomer reactions and inhibitions compared with experimental data. The substrate and enzyme have initial properties of (a) 20 g/L Avicel and 4.1 g/L Spezyme CP [9] and (b) 10 g/L Avicel and 0.51 g/L Spezyme CP together with 30 IU beta-glucanase/g Avicel (57.69 mg/L beta-glucanase) [10]. Commercial enzyme Spezyme CP consists EG1, CBHI and CBHII in a mass ratio of 0.17:0.24:0.13 (EG1/CBHI/CBHII) [17].
