木质素对纤维素酶水解抑制作用的研究进展与展望

The research progress and prospect on lignin inhibition in cellulose enzyme hydrolysis

木质纤维素原料作为新一代生物乙醇发酵的原料备受关注,但在实际生产制备过程中木质纤维素中木质素的存在对纤维素酶水解纤维素这一过程产生了抑制作用,限制了木质纤维素资源在生物乙醇发酵方面工业化规模的推广与应用。本文通过归纳近年来有关减少木质素对纤维素酶水解的抑制、提高酶水解效率的研究进展,明确提出了推动木质纤维生物质炼制实现工业化所需深入探索的策略和方向。

Lignocellulose materials as a new generation of bioethanol have attracted much attention. In the practical application, the lignins always block the active positions of cellulase during the hydrolytic process, which limited the ethanol fermentation using lignocelluloses as raw materials to develop in industrial scale popularization and application. In this paper was summarized how to improve cellulase hydrolysis efficiency and how to reduce the negative effects of lignin during the enzyme hydrolysis process have been developed in recent years.The further study purpose and direction have been pointed out definitely.
