嗜酸乳杆菌和婴儿双歧杆菌对肠道致病菌的抑制性

Study on the growth inhibition of some pathogens by the L.acidophilus and B.infantis

通过实验菌株发酵液对三种肠道致病菌生长抑制的研究 ,得出嗜酸乳杆菌 PB1、A878和婴儿双歧杆菌 PBa对致病菌的抑制性较强 ,形成明显的抑菌圈。 PB1、A878、PBa的抑菌机理主要是有机酸 。

The gowth inhibition of some pathogens by the fermented liquor of probiotic bacteria were tested.The results indicated that growth of three pathogens were strongly inhibited by L.acidophilus PB1,A878 and B infantis PBa.The diameter of inhibition zone was clear.The inhibition mechanisms of PB1,A878,PBa were some organic acids and antibacterial substance in fermented liquor was not important.
