Abstract

It is very important to rapidly detect the contamination of Enterococcus faecalis in fermented foods such as Korean Kimchi to maintain its freshness since Kimchi is exported to all over the world. However, gene sequence of E. faecalis is very similar among various Lactobacillus. So, there have been difficulties in its screening. We have designed primers based on Bile salt hydrolase gene of E. faecalis and applied them to PCR test. PCR band was identified only from E. faecalis and only from the mixture contaminated with E. faecalis. It means that the primers we designed are highly specific for distinguishing contamination of E. faecalis. It will be possible to precisely screen within 1h, which will greatly contribute to the prevention of food poisoning and quick quarantine.
