Polysaccharides are natural chemical compounds that are extensively employed in the food and pharmaceutical industries. They exhibit a wide range of physical and biological properties. These properties are commonly improved by using chemical and physical methods. However, with the advancement of biotechnology and increased demand for green, clean, and safe products, polysaccharide modification microbial fermentation has gained importance in improving their physicochemical and biological activities. The physicochemical and structural characteristics, biological activity, and modification mechanisms of microbially fermented polysaccharides were reviewed and summarized in this study. Polysaccharide modifications were categorized and discussed in terms of strains and fermentation techniques. The effects of microbial fermentation on the physicochemical characteristics of polysaccharides were highlighted. The impact of modification of polysaccharides on their antioxidant, immune, hypoglycemic, and other activities, as well as probiotic digestive enhancement, were also discussed. Finally, we investigated a potential enzyme-based process for polysaccharide modification microbial fermentation. Modification of polysaccharides microbial fermentation has significant value and application potential.
多糖是一种广泛应用于食品和制药行业的天然化合物，具有广泛的物理和生物特性。这些特性通常可以通过化学和物理方法来改善。然而，随着生物技术的进步和对绿色、清洁、安全产品的需求增加，多糖修饰微生物发酵在提高其物理化学和生物活性方面变得越来越重要。本研究综述和总结了微生物发酵多糖的理化和结构特性、生物活性和修饰机制。根据菌株和发酵技术对多糖修饰进行了分类和讨论。强调了微生物发酵对多糖物理化学特性的影响。还讨论了多糖修饰对其抗氧化、免疫、降血糖等活性以及益生菌消化增强的影响。最后，我们研究了一种潜在的基于酶的多糖修饰微生物发酵过程。多糖修饰微生物发酵具有重要的价值和应用潜力。
