Bacterial exopolysaccharides are high molecular weight polysaccharides that are secreted by a wide range of bacteria, with diverse structures and easy preparation. Fucose, fucose-containing oligosaccharides (FCOs), and fucose-containing polysaccharides (FCPs) have important applications in the food and medicine fields, including applications in products for removing and infant formula powder. Fucose-containing bacterial exopolysaccharide (FcEPS) is a prospective source of fucose, FCOs, and FCPs. This review systematically summarizes the common sources and applications of FCPs and FCOs and the bacterial strains capable of producing FcEPS reported in recent years. The repeated-unit structures, synthesis pathways, and factors affecting the production of FcEPS are reviewed, as well as the degradation methods of FcEPS for preparing FCOs. Finally, the bioactivities of FcEPS, including anti-oxidant, prebiotic, anti-cancer, anti-inflammatory, anti-viral, and anti-microbial activities, are discussed and may serve as a reference strategy for further applications of FcEPS in the functional food and medicine industries.
细菌胞外多糖是由多种细菌分泌的高分子量多糖，具有多样的结构且易于制备。岩藻糖、含岩藻糖的寡糖（FCOs）和含岩藻糖的多糖（FCPs）在食品和医药领域有重要应用，包括在去除产品和婴儿配方奶粉中的应用。含岩藻糖的细菌胞外多糖（FcEPS）是岩藻糖、FCOs和FCPs的一个潜在来源。本文综述系统总结了FCPs和FCOs的常见来源及应用，以及近年来报道的能够产生FcEPS的细菌菌株。综述了FcEPS的重复单元结构、合成途径、影响其产生的因素，以及用于制备FCOs的FcEPS降解方法。最后，讨论了FcEPS的生物活性，包括抗氧化、益生元、抗癌、抗炎、抗病毒和抗菌活性，可为FcEPS在功能性食品和医药行业的进一步应用提供参考策略。
