10个拟杆菌属研究人员调查了在人类结肠中发现的酵母菌发酵粘蛋白和植物多糖（膳食纤维）的能力。许多菌株发酵粘多糖（肝素，透明质酸和硫酸软骨素）和卵类粘蛋白。188株菌中只有3株能发酵牛颌下粘蛋白，没有一株能发酵猪胃粘蛋白。许多测试的拟杆菌菌株也能够发酵各种植物多糖，包括直链淀粉、葡聚糖、果胶、黄蓍胶、瓜尔胶、落叶松阿拉伯半乳聚糖、藻酸盐和海带多糖。一些植物多糖，如阿拉伯胶、刺梧桐树胶、印度胶和岩藻依聚糖，不被任何测试的菌株利用。利用粘蛋白和植物多糖的能力在拟杆菌属中差异很大。测试[B.脆弱B vulgatus，B. Thetaiotaomicron，B. distasonis，B. ovatus和B. eggerthii]。
Ten Bacteroides spp. found in the human colon were surveyed for their ability to ferment mucins and plant polysaccharides (dietary fiber). A number of strains fermented mucopolysaccharides (heparin, hyaluronate and chondroitin sulfate) and ovomucoid. Only 3 of the 188 strains tested fermented beef submaxillary mucin, and none fermented porcine gastric mucin. Many of the Bacteroides strains tested were also able to ferment a variety of plant polysaccharides, including amylose, dextran, pectin, gum tragacanth, gum guar, larch arabinogalactan, alginate and laminarin. Some plant polysaccharides, such as gum arabic, gum karaya, gum ghatti and fucoidan, were not utilized by any of the strains tested. The ability to utilize mucins and plant polysaccharides varied considerably among the Bacteroides spp. tested [B. fragilis, B. vulgatus, B. thetaiotaomicron, B. distasonis, B. ovatus and B. eggerthii].
