摘要: 甘露聚糖是软质木材中的重要多糖。不同植物来源的甘露聚糖在成分、结构和复杂性上差异很大。甘露聚糖水解为单糖需要甘露聚糖酶、甘露糖苷酶、半乳糖苷酶等多种酶的协同作用,但研究其两者或三者之间的作用较少。为了进一步探究甘露聚糖酶协同水解甘露聚糖的作用机制,本文在概述甘露聚糖来源及结构的基础上,重点论述了甘露聚糖酶的来源、种类、作用方式及产物类型,尤其是通过多种甘露聚糖酶的协同作用增加甘露聚糖的水解效率。最后,展望了甘露聚糖酶协同作用进程与机理的研究方向,为甘露聚糖酶开发利用提供基础。

Abstract: Mannan is an important polysaccharide found in softwoods. Mannans from various sources display large differences in composition, structure and complexity. To hydrolysis mannans into monomer sugars requires a number of enzymes like mannanases, mannosidases and galactosidases working in synergy, but several studies have investigated the effect of the two or three. In order to explore the mechanism of mannanase synergistic hydrolysis of mannan, this paper stated mannans’ sources and its structure firstly. Then the sources, species, action mode of mannanase and product type were summarzied, especially the high efficiency of the synergistic enzymatic hydrolysis of mannans by mannanase. Finally, this paper prospected the research direction of process and mechanism of mannanase’s synergistic reaction, and provided the basis for the development and utilization of mannanase.
