| 摘 要： | 为了解水苏糖、低聚异麦芽糖、低聚果糖3种益生元对青春双歧杆菌耐胆盐能力的影响情况,该研究在PTYG液体培养基中分别添加不同浓度的3种益生元.并在不同的胆盐浓度梯度下进行青春双歧杆菌耐胆盐能力的研究.结果表明,3种益生元均可提高青春双歧杆菌耐胆盐能力,低聚异麦芽糖的效果最好;在猪胆盐浓度为0.3%的PTYG液体培养基中,水苏糖、低聚异麦芽糖、低聚果糖提高青春双歧杆菌耐胆盐能力的最适添加量分别为1.0%、1.5%、O.2%,其中低聚异麦芽糖的添加量(1.5%)提高青春双歧杆菌耐胆盐能力的效果最好.

| Abstract: | Using B.adolescentis as study strain,bile resistant ability affected by stachyose,isomaltoligosaccharide,and fructo-oligosaccharide were studied by addition of different concentrations of prebiotics and bile in liquid PTYG medium.The results showed that prebiotics,stachyose,isomaltoligosaccharide,and fructo-oligosaccharide could increase bile resistant ability,and isomaltoligosaccharide was the best.In the liquid medium with 0.3% of pig source bile,the optimum addition of stachyose,isomaltoligosaccharide,an... |
