Method: The bacteriocin, which named enterocin CMUL20-2 was secreted by Enterococcus faecium CMUL20-2. This bacterial strain was originally isolated from raw goat’s milk, was extracted by using a modified adsorption-desorption method and purified via RP-HPLC. antimicrobial activity was tested against several pathogenic and spoilage microbes. Results: The enterocin CMUL20-2 showed a strong adsorption on cell wall of producer strain even in acidic environment which facilitate its extraction in only two simple steps. The recovered purified enterocin has decreased procedure time and diminished the number of undesirable molecules present in Rogosa and Sharpe (MRS) broth. The recovered enterocin showed antimicrobial activity against several foodborne pathogenic and spoilage microbes. Conclusion:  The recovered enterocin was able to tolerate a variety of food chain conditions such as high temperature, pH and storage stability, and it can be a good candidate to protect food from spoilage microbes.  Show less >
