摘要
通过测定菌体培养液吸光值的方法,进行茯苓发酵产物提取液(FPE)对乳杆菌和双歧杆菌的增殖效果体外实验。结果表明:与异麦芽低聚糖(IMO)和低聚果糖(FOS)相比,添加了FPE的培养基可以更好的促进双歧杆菌的生长(P <0.01),说明FPE可以作为一种双歧因子,促进双歧杆菌的增殖。培养基中FPE的浓度为2.5%~5%时对双歧杆菌和乳杆菌的增殖效果最好。在添加了FPE的培养基中生长的双歧杆菌的生长迟缓期较在未添加的基础培养基中更短,添加FPE的培养液的吸光值明显大于未添加培养液(P<0.01),说明发酵产物提取液可以作为一种有效的益生元促进二者生长。
The effect on the proliferation of Bifidobacterium and Lactobacillus by extracts from poria cocos solidfermentation products (FPE)was tested in vitro.The results demonstrated FPE could be a bifidusfactor to promote the proliferation of Bifidobacterium.Compared with other bifidusfactors,such as isomalto oligosaccharides and fructo oligosaccharides,FPE could significantly promote the growth of Bifidobacterium (P <0.01).High concentration of FPE inhibited the proliferation of Bifidobacterium and Lactobacillus.The best concentration of FPE was from 2.5% to 5%.The absorbance of culture liquid containing FPE was higher than the control group's (P <0.01).Therefore,the extract can be used as a prebiotic to promote the growth of Bifidobacterium and Lactobacillus.
