| 摘 要： | 褐藻胶是褐藻中含有的酸性多糖,由β-D-甘露糖醛酸及其C5差向异构体α-L-古罗糖醛酸两种单体组成。经降解后的小分子寡糖具有增强植物抗逆性、促进生长作用、抗菌活性、抗肿瘤活性、抗炎活性以及抗氧化活性等多种生理活性。目前,褐藻胶寡糖制备的方法主要有化学降解法、物理降解法和生物降解法。本文概述了褐藻胶结构、褐藻胶降解方法以及褐藻胶寡糖生理活性研究现状,其中重点介绍了生物降解的方法,并对褐藻胶裂解酶及其降解产物的应用进行了展望。

| Abstract: | Alginate is an acid polysaccharide contained in brown algae, which is composed of β-d-mannose uronic acid and its C5 isoform α-l-guluronic acid. The degraded oligosaccharides have many physiological activities, such as strengthening plant stress resistance, promoting growth, antibacterial activity, anti-tumor activity, anti-inflammatory activity and antioxidant activity. At present, the preparation methods of algin oligosaccharide mainly include chemical degradation, physical degradation and biological degradation. In this paper, the structure of alginate, the degradation methods of alginate and the physiological activities of alginate oligosaccharides are summarized, the biodegradation methods are emphasized, and the application of alginate lyase and its degradation products is prospected. |
