摘　　要：市售活菌制剂口服液活菌数急剧衰降的原因是营养缺乏，特别是缺乏部分氨基酸及某些维生素。增加动物性蛋白胨及强化酵母膏，添加适量维生素可使活菌数一年后保持在１０６／ｍｌ以上。The reason that the number of living cells in living bacteria preparation of oral liquidsold in the market suddenly attenuate is because lack of nutrition, particularly, the partialamino-acid and partial vitamin within the protein.Increasing the animal peptone and thestrengthened yeast extract,the number of living cells can be kept at the level of 10￣6/ml after oneyear's storage.
