【Objective】

We examined antibacterial activities of Enterococcus faecalis TH10 against Escherichia coli O157.

【Methods】

We extracted culture supernatant fluids of Enterococcus faecalis TH10. We prepared the extract apt for the test and performed an antibacterial test with a paper disk method.

【Results】

The prepared extract from culture supernatant fluids of Enterococcus faecalis TH10 showed a potent antibacterial activity against Escherichia coli O157. The antibacterial active substances in the extract did not affect to Enterococcus genus. We considered that Enterococcus faecalis TH10 is different from bacteriocin which shows antibacterial activity against the related species of lactic acid bacteria.
