Abstract:

In order to obtain the candidate strains of probiotics, twenty-two Lactic acid bacteria were isolated from the jejunum content of ducks, and the strain ZW001 was researched in this article. According to the results of morphological observation, physiological and biochemical test, 16S rDNA sequence homology analysis, the strain ZW001 was identified as Pediococcus acidilactici. Moreover, the healthy function of the strain, such as acid resistance, bile salt tolerance, high temperature tolerance and antibacterial activity, was researched by us. The results showed that strain ZW001 had good the stress tolerance, and exhibited good antibacterial activity. In conclusion, these properties make the strain ZW001 promising for application in the feed industry.
