直投式酸奶发酵剂中双歧杆菌的分离

Isolation of Bifidobacterium from Direct Yoghurt Fermenter

介绍一种简便可行的从直投式酸奶发酵剂中分离双歧杆菌的方法。发酵剂在液体培养基中活化后,在不同选择培养基上划线分离,根据菌落及菌体形态确定双歧杆菌。然后进行初步鉴定。

An easy, simple, and feasible method to isolate Bifidobacterium from direct yoghurt fermenter is introduced. After the fermenter was cuhured and activated in liquid medium, it was separated on different media with scratch method. Bifidobacterium confirmed according to its colony and cell form, then to carry out the initial characterization.
