| 摘 要： | 目的:建立发酵乳中双歧杆菌数量计数测定方法。方法:采用果糖为碳源的鉴别培养基,基于乳酸菌同型发酵和异型菌落形态的差异,借助pH指示剂确定样品中双歧杆菌数量。结果:该培养基所计双歧杆菌数量与对照培养基所计数量在同一数量级且差异不显著(P>0.05)。结论:该培养基可用于发酵乳中双歧杆菌的准确计数。

| Abstract: | Objective:To establish a quantitative method for bifidobacterium in fermented milk.Methods:A differential culture medium,which use fructose as the only source of carbohydrates,was emploied to quantitatively assess bifidobacterium,based on a morphological differentiation of colonies and a counting of bifidobacterium on the same plate.Results:Results obtained with FBM are very close to those obtained by the use of reference media(P>0.05).Conclusion:FBM medium is situble for enumering Bifidobacterium in fermented milk |
