一种胞外多糖及其应用
摘要：
本发明公开了一种胞外多糖及其应用，属于生物工程技术领域。本发明的此胞外多糖(EPS)是由保藏编号为CCTCC NO:M 2018426的丁酸梭菌(Clostridium butyricum)分泌得到的一种由氨基葡萄糖、阿拉伯糖、氨基半乳糖、半乳糖、葡萄糖以及甘露糖构成的杂多糖，它具有比抗坏血酸更高的清除自由基能力；能够为AAPH以及羟基自由基诱导的氧化应激提供良好的DNA保护作用；同时，还可以防止紫外辐射对DNA活性的直接破坏。
摘要（英）：

The invention discloses an exopolysaccharide and application thereof, belonging to the technical field of bioengineering. The exopolysaccharide (EPS) is a heteropolysaccharide formed by glucosamine, arabinose, galactosamine, galactose, glucose and mannose secreted from clostridium butyricum (Clostridium Butyricum) with a preservation number of CCTCC NO:M 2018426 and has relatively high free radical scavenging capacity than ascorbic acid; a good DNA protection effect can be provided for oxidative stress induced by AAPH and hydroxyl free radicals; and meanwhile, the direct damage caused by ultraviolet radiation to the activity of DNA.
