Probiotics, prebiotics and synbiotics are frequently-used components for the elaboration of functional food. Currently, most of the commercialized probiotics are limited to a few strains of the genera Bifidobacteria, Lactobacillus and Streptococcus, most of which produce exopolysaccharides (EPS). This suggests that the beneficial properties of these microorganisms may be related to the biological activities of these biopolymers. In this work we report that a 2-substituted-(1,3)-β-d-glucan of non-dairy bacterial origin has a prebiotic effect on three probiotic strains. Moreover, the presence of this β-d-glucan potentiates in vitro adhesion of the probiotic Lactobacillus plantarum WCFS1 to human intestinal epithelial cells.
益生菌、益生元及合生元是用于制作功能性食品的常用成分。目前，大多数商业化的益生菌仅限于双歧杆菌属、乳杆菌属和链球菌属的少数菌株，其中大多数会产生胞外多糖（EPS）。这表明这些微生物的有益特性可能与这些生物聚合物的生物活性有关。在本研究中，我们报道了一种非乳制品来源的2-取代-(1,3)-β-D-葡聚糖对三种益生菌菌株具有益生元作用。此外，这种β-D-葡聚糖的存在增强了益生菌植物乳杆菌WCFS1对人肠上皮细胞的体外黏附。
