Exopolysaccharides have prebiotic potential and contribute to the rheology and texture of fermented foods. Here we have analyzed the in vitro bioavailability and immunomodulatory properties of the 2-substituted (1,3)-beta-D-glucan-producing bacterium Pediococcus parvulus 2.6. It resists gastrointestinal stress, adheres to Caco-2 cells, and induces the production of inflammation-related cytokines by polarized macrophages.
胞外多糖具有益生元潜力,并对发酵食品的流变学和质地有贡献。在此,我们分析了产2-取代(1,3)-β-D-葡聚糖的短小乳杆菌2.6的体外生物利用度和免疫调节特性。它能抵抗胃肠道应激,黏附于Caco-2细胞,并诱导极化巨噬细胞产生炎症相关细胞因子。
