摘要
不论是在自然或病理条件下,多数细菌均被胞外多糖所包被,胞外多糖对细菌的粘附及在竞争环境中的存活和生长都具有重要作用。近年来细菌胞外多糖以其独特的生物学活性和广阔的应用前景而备受人们关注。系统介绍了细菌胞外多糖的结构性质、特性及生理功能,重点阐述了几种多糖的应用现状,并对今后细菌胞外多糖在工业上的发展趋势进行了展望,为深入开发利用多糖功能菌资源,进一步扩展其在工业领域上的应用奠定理论基础。
The majority of bacteria are packaged by extracellular polysaccharides,which play an important role in their survival and growth,whether in nature or pathological conditions.The unique bioactivities of bacterial expolysaccharides and their application prospects were paid great attention by the concerned people.The structure,physical and chemical characteristics,biological activities of polysaccharides produced by bacterium were introduced in detail in this paper,especially the application of several bacterial expolysaccharides in industry.The future development of bacteria polysaccharides was envisaged.It provides theoretical basis for the further development of functional bacteria and expansion of application of bacterial exopolysaccharides in industrial.
