3种低聚糖对两歧双歧杆菌BB03生长的影响

摘要

以MRS培养基为对照,研究了不同浓度的水苏糖、低聚木糖及低聚半乳糖对两歧双歧杆菌BB03生长的影响.结果表明,在MRS培养基中添加0.2%～1.0%的水苏糖在前期能加速两歧双歧杆菌的生长,最佳添加量为1.0%,低聚木糖的最适添加量为0.8%,低聚半乳糖的最适添加量为0.6%.%Effects of three oligosaccharides including stachyose, xylooligosaccharide(XOS), and galatooligosaccharide(GOS) on growth of Bifidobacterium bifidum BB03 were studied using MRS media as control. The result showed taht addition of stachyose by 0.2％～1.0％ in MRS medium had positive effect on growth of B. bifidum BB03 at beginning phase and the optimum concentration was 1.0％. The optimum addition of xylooligosaccharide and galatooligosaccharide was 0.8％ and 0.6％, respectively.
