纤维素酶法水解的研究现状及展望

Research progress and prospect on the enzymic hydrolysis for cellulose

纤维素是地球上最丰富的天然高分子化合物,可以通过水解的方法将其转化为为人类生产生活服务的能源、食物及化工原料。而早期水解纤维素主要采用酸水解法,但由于要求条件高,产率低, 以及对环境存在污染,现已被淘汰。近年来,随着生物技术的迅速发展以及具有催化高效性的酶的研究,人们开始试图利用纤维素酶来水解纤维素,以期达到充分利用的目的。作者就纤维素酶法水解的研究进展及应用作了简要的概述。

Cellulose is the most abundant natural macromolecular, which can be hydrolyzed to get energy, food and chemical industrial material. The acid hydrolysis for cellulose, which possesses deficiencies such as strict conditions,low production and environmental pollution, have been cancelled. Recently, people have being researched enzymic hydrolysis for cellulose due to the development of biotechnology and the high efficiency of enzyme. The article summarizes the present study progress and the application of enzymic hydrolysis for cellulose.
