| Abstract: |
| 【Objective】This research studied the physiological characteristics and antimicrobial ability of Rex Rabbit bifidobacterium.【Method】After Rex Rabbit bifidobacteria were inoculated in indicated medium,the growth characteristics were investigated.And the antimicrobial activity of Rex Rabbit bifidobacterium was detected through co-culturing with E.coli.【Result】Rex Rabbit bifidobacteria were cladodromous and significantly proliferated in improved broth.It was found through heat-resistant assay that Rex Rabbit bifidobacterium could grow at 42 ℃.Rex Rabbit bifidobacteria were sensitive to many drugs like Erythromycin.After Rex Rabbit bifidobacterium were co-cultured with E.coli,the growth of E.coli was blocked and the metabolites from Rex Rabbit bifidobacterium also had obvious antimicrobial function.【Conclusion】Rex Rabbit bifidobacteria grew well in vitro and had significant antimicrobial activity. |
