为探究燕麦活性糖组分对加氏乳杆菌(L.gasseri)肠道耐受性和降胆固醇作用的影响，评估不同质量浓度的燕麦β-葡聚糖、水苏糖及阿拉伯木聚糖等活性糖组分对L.gasseri体外生长特性、胁迫耐受性(耐酸与耐胆盐能力)及其降解胆固醇能力的调控作用。结果表明：阿拉伯木聚糖是燕麦中增强L.gasseri肠道耐受性和降胆固醇能力的关键活性糖组分，其综合促进效果显著优于β-葡聚糖、水苏糖和低聚果糖等其他组分。
Abstract：To investigate the effects of oat active saccharide components on the intestinal tolerance and cholesterol-lowering activity of Lactobacillus gasseri, the influence of different mass concentrations of oat β-glucan, stachyose, and arabinoxylan on the growth characteristics, stress tolerance(acid and bile salt resistance) of L. gasseri in vitro, and its cholesterol-lowering ability were evaluated. The results demonstrated that arabinoxylan serves as the key active saccharide component in oats for enhancing the intestinal tolerance and cholesterol-lowering capacity of L. gasseri. Overall promoting effect of arabinoxylan was markedly superior to that of other components, including β-glucan, stachyose, and fructooligosaccharide.
