摘要
纤维素水解转化为可发酵糖工艺是纤维素乙醇炼制过程中至关重要的环节。酶法水解工艺具有条件温和、副产物少、环境友好等特点,因而受到广泛重视。目前许多学者已针对如何提高木质纤维素酶解效率、降低纤维素酶成本等问题,开展了多种化学、生物技术及工艺耦合的研究。本文综述了近几年木质纤维素酶解领域取得的最新工艺进展和理论研究成果,对原料预处理、多酶复配优化、酶脱附与重复利用、工艺耦合、高固液比反应等方面的研究情况进行了总结,同时展望了木质纤维素酶解工艺的未来发展方向。
The key issue for the industrialization of cellulosic ethanol is the conversion of lignocellulosic feedstocks into fermentable sugars. Enzymatic hydrolysis of conditions, fewer by-products and environmental lignocellulose has caught much attention because of its modest reaction benignity. A lot of chemical and biochemical technologies are developed to enhance the efficiency of 1ignocellulose hydrolysis or to reduce the cost of cellulase. In this paper, the effects of pretreatment methods, highly efficient enzyme mixtures, recycling of enzyme, integrated technologies and high solid substrate concentration on the efficiency of lignocellulose conversion are reviewed in details. The progress and prospects on enzymatic hydrolysis of lignocellulosic materials are also presented.
