摘　　要：从中年人粪便中分离到136株可疑双歧杆菌,通过耐氧力测定获得一株耐氧性菌.经属和种的系统生理生化鉴定,确认为长双歧杆菌(Bifidobacterium longum).小范围饮用实验结果表明,该菌对便秘有疗效.This paper reports 136 strains suspected to he species of the genes Bifidobacterium isolated from adult human feaees. Through detecion of the ability to tolerate molecular oxygen in curtural environments, we obtained an oxygen-resistant strain TQ21-2-2 according to the Bergy's mannual. It was identified as Bifidobacterium Longum. A limited number of drinking the beverage, the experiment also using this strain in milk as a starter revealed that this strain has been found useful for treating cases with compisation.
