【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。
[Abstract]:The effects of oligosaccharide on growth of bifidobacterium pubertifolia and bifidobacterium animal were studied in vitro. Using oligosaccharide of Chinese yam as carbon source, it was found that oligosaccharide could promote the growth of bifidobacterium and bifidobacterium in vitro: with the addition of oligosaccharide, Chinese yam oligosaccharide could promote the growth of bifidobacterium pubescens and bifidobacterium in vitro. The number of living bacteria in the culture medium increased and decreased. When oligosaccharide replaced glucose and the mass fraction was 0.5, the maximum growth of Bifidobacterium puberty and Bifidobacterium animal were increased by 10.70 卤4.93% and 6.02 卤2.00%, respectively, and decreased by 2.64 卤0.001% and 3.85 卤0.65%, respectively. At the same time, Chinese yam oligosaccharides can increase the growth rate of bifidobacterium puberty and bifidobacterium animal, so that the growth of bifidobacterium can advance into the stable period.
