Carrageenan, agarose, and alginate are algae-derived undigested polysaccharides that have been used as food additives for hundreds of years. Fermentation of dietary carbohydrates of our food in the lower gut of humans is a critical process for the function and integrity of both the bacterial community and host cells. However, little is known about the fermentation of these three kinds of seaweed carbohydrates by human gut microbiota. Here, the degradation characteristics of carrageenan, agarose, alginate, and their oligosaccharides, by , , and , isolated from human gut microbiota, are studied.
角叉菜胶、琼脂糖和藻酸盐是源自藻类的未消化多糖，数百年来一直被用作食品添加剂。人类食物中的膳食碳水化合物在肠道下段的发酵是细菌群落和宿主细胞功能及完整性的关键过程。然而，关于这三种海藻碳水化合物被人类肠道微生物群发酵的情况却知之甚少。在此，研究了从人类肠道微生物群中分离出的 、 和 对角叉菜胶、琼脂糖、藻酸盐及其寡糖的降解特性。
