微生物产胞外多糖研究进展

Research Progress of Exopoly Saccharide Produced by Microorganisms

近年来,微生物产胞外多糖(EPS)因能改善食品质量、调节肠道菌群、抗氧化、抗肿瘤、免疫预防及防治心脑血管疾病的功能特性而受到关注,并通过研究者的逐渐深入研究和各种方法修饰EPS结构,以增强其功能。目前,国内对微生物EPS的研究仍处于初级阶段,仍需进一步探索。综述了国内外微生物产EPS的分类、生物合成、结构修饰、功能特性及其应用方面的最新进展,分析了不同种类EPS的生物合成途径和结构特点,以及通过物理、化学和生物方法对其进行功能性修饰的策略,为相关领域的研发提供新的参考,促进EPS在食品、医药及工业领域的应用和产业化发展。

In recent years,exopoly saccharides(EPS) produced by microorganisms have garnered attention due to their functional properties such as improving food quality,regulating intestinal microbiota,antioxidative effects,anticancer properties,immunoprevention,and treatment of cardiovascular diseases.Currently,research on microbial EPS(extracellular polymeric substances) in China is still in its early stages and requires further exploration.This paper comprehensively reviewed the latest advancements in the classification,biosynthesis,structural modification,functional properties,and applications of EPS produced by microorganisms both domestically and internationally.This study also focused on analyzing the biosynthetic pathways and structural features of different types of EPS,as well as the strategies for functional modification through physical,chemical,and biological methods.The aim is to provide new references and guidance for research and development in relevant fields,thereby promoting the application and industrialization of EPS in the food,pharmaceutical,and industrial sectors.
