| Abstract: |
| Conversion efficiency of lignocelluloses to ethanol is influenced by many factors. In this work, enzymatic saccharification of pretreated rice straw was explored in four additives（Tween-80, PEG 6000, BSA and [BMIM]Cl） with and without different electric field strengths from two parallel electrodes. Saccharification efficiency was 26.6% greater at 12 V·m-1 of electric field strength than the control. At this electric field strength, applying Tween-80 at 200 μL·g-1, PEG 6000 at 40 mg·g-1 and BSA at 20 mg·g-1 further enhanced saccharification efficiency. However, ionic liquid [BMIM]Cl had inhibition to enzymatic saccharification of rice straw. The experimental results indicate that proper additives such as Tween-80, PEG 6000 and BSA could effectively improve efficiency of enzymatic saccharification of lignocellulose with parallel electric field, with BSA showing the greatest efficiency of lignocellulosic saccharification. |
