摘要:

蔗糖占我国食糖总消费量90%以上，而甘蔗是蔗糖的主要原材料。然而，我国甘蔗生产集约化程度低，导致制糖成本越来越高，提高甘蔗及副产品的资源化利用水平，对我国甘蔗制糖产业具有重要意义。本文综述近年来甘蔗基蔗糖高附加值生物转化利用方面的研究进展，总结蔗糖生物催化相关的关键酶元件，以及多酶级联催化技术转化蔗糖制备结构多样性功能产品方面的应用，阐述微生物发酵技术利用蔗糖及糖蜜制备大宗化学品和精细化学品方面的潜力，进一步探讨甘蔗基蔗糖高附加值利用的研究方向。

Abstract:

Sucrose accounts for more than 90% of total sugar consumption in China,and sugarcane is the main raw material of sucrose.However,the low intensive level of sugarcane production in China has made the sugar costs higher and higher.It is of great significance for China's sugarcane industry to increase the utilization level of sugarcane and its by-products.In this article,the recent advances in biotransformation and utilization from sugarcane-based sucrose to high value-added products were reviewed and the key enzyme modules related to sucrose biocatalysis were summarized.The application of multiple-enzyme cascade catalysis to produce diverse products from sucrose was also reviewed.The potential of microbial fermentation in utilizing sucrose and molasses to prepare bulk and fine chemicals was introduced.Furthermore,the future direction in high value-added utilization of sugarcane-based sucrose was further explored.
