摘　　要：利用体外模型探讨了山药低聚糖对青春双歧杆菌和动物双歧杆菌的生长促进作用。以山药低聚糖取代葡萄糖为碳源添加到双歧杆菌基础培养基中,发现山药低聚糖对青春双歧杆菌和动物双歧杆菌的体外生长具有显著促进作用:随着山药低聚糖的加入,培养液中活菌数增加,p H值降低。当山药低聚糖取代葡萄糖且质量分数为0.5%时,青春双歧杆菌和动物双歧杆菌的最大生长量分别提高了(10.70±4.93)%和(6.02±2.00)%;p H值分别下降(2.64±0.001)%和(3.85±0.65)%。同时,山药低聚糖可提高青春双歧杆菌和动物双歧杆菌的生长速率,使其生长提前进入稳定期。In the present work,the growth-promoting effects of Chinese yam oligosaccharides on Bifidobacteriumadolescentis and Bifidobacterium animals in vitro were examined.Being used as a substitute of carbon source for glucosein culture medium,Chinese yam oligosaccharides had significant promoting effects on the growth of bifidobacteria.Withthe increase in added Chinese yam oligosaccharides,the viable count of the probiotic bacteria increased,while the pHvalue decreased.By glucose substitution with0.5%Chinese yam oligosaccharides,the viable counts of B.adolescentis andB.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 oligosaccharides promoted the growth rate of bifidobacteria andresulted in earlier onset of the stationary growth phase.
