卡拉胶、琼脂糖和藻酸盐是藻类衍生的未消化的多糖，数百年来一直用作食品添加剂。食物中的碳水化合物在人类下消化道中的发酵是细菌群落和宿主细胞功能和完整性的关键过程。然而，人们对这三种海藻碳水化合物在人体肠道微生物群中的发酵知之甚少。在这里，降解特性的卡拉胶，琼脂糖，海藻酸盐，和他们的寡糖，木聚糖溶拟杆菌，卵形拟杆菌，和均匀拟杆菌，分离自人类肠道微生物群，进行了研究。
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 Bacteroides xylanisolvens, Bacteroides ovatus, and Bacteroides uniforms, isolated from human gut microbiota, are studied.
