Abstract: The microecological stability of the freeze-dried powder of Bacillus natto was investigated. The results showed thatthe powder could resist acid, alkali, pepsin, trypsin and gallbladder salt, to assure that enough Bacillus natto could successfullypass and survive in the intestines and play their role of microecological activity. Moreover, the powder shows excellent stabilitiesduring room temperature storage for 120 days after 80℃ heat treatment for 60 minutes, However, it shows less stable after-20℃ storage.

Key words: Bacillus natto, microecologics, stability
