Organisms able to grow on arabinogalactan, pectin, xylan, wheat bran, guar, apple cell walls, and mucin were isolated by enrichment from human feces. The number of polysaccharide fermenters and the properties of the predominant bacteria varied between subjects. The ability to use one polysaccharide was not related to the ability to use others. Some organisms (e.g., Bacteroides spp.) isolated on other substrates also utilized mucin, but were not isolated in the mucin enrichment. The mucin fermenters isolated by enrichment had a very restricted ability to utilize complex polysaccharides and their constituent monosaccharides, suggesting that the presence of plant polysaccharides in the human colon is unlikely to prevent the use of colonic mucin as an energy source by bacteria. Characterization with a range of biochemical tests showed that many of the isolates, but especially the mucin fermenters, did not resemble organisms described previously.
通过从人类粪便中富集培养，分离出了能够在阿拉伯半乳聚糖、果胶、木聚糖、麦麸、瓜尔豆胶、苹果细胞壁和粘蛋白上生长的微生物。多糖发酵菌的数量以及主要细菌的特性在不同个体之间存在差异。利用一种多糖的能力与利用其他多糖的能力无关。在其他底物上分离出的一些微生物（如拟杆菌属）也能利用粘蛋白，但在粘蛋白富集培养中未被分离出来。通过富集培养分离出的粘蛋白发酵菌利用复杂多糖及其组成单糖的能力非常有限，这表明人类结肠中植物多糖的存在不太可能阻止细菌将结肠粘蛋白作为能量来源。一系列生化测试表明，许多分离株，尤其是粘蛋白发酵菌，与先前描述的微生物不同。
