ISOLATION AND IDENTIFICATION OF AN OXYGEN-TOLERANT STRAIN OF BIFIDOBAC-TERIUM FROM HUMAN FECES
耐氧双歧杆菌的分离和鉴定

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.
