山药低聚糖对2种双歧杆菌的体外促生长作用
Promoting Effects of Oligosaccharides from Chinese Yam on the Growth of Two Species of Bifidobacteria in Vitro
摘要
Abstract
In the present work,the growth-promoting effects of Chinese yam oligosaccharides on Bifidobacterium adolescentis and Bifidobacterium animals in vitro were examined.Being used as a substitute of carbon source for glucose in culture medium,Chinese yam oligosaccharides had significant promoting effects on the growth of bifidobacteria.With the increase in added Chinese yam oligosaccharides,the viable count of the probiotic bacteria increased,while the pH value decreased.By glucose substitution with 0.5％ Chinese yam oligosaccharides,the viable counts ofB.adolescentis and B.animals increased by (10.70 ± 4.93)％ and (6.02 ± 2.00)％,respectively,and the pH value decreased by (2.64 ± 0.001)％ and (3.85 ± 0.65)％ respectively.Meanwhile,Chinese yam oligosacchaddes promoted the growth rate of bifidobacteria and resulted in earlier onset of the stationary growth phase.关键词
