Identification ofthe first bacteriocin isolated in Lebanon extracted viaa modified adsorption-desorption method andits potential food application
Abstract
Introduction: The raw goat milk is considered as a good source of
novel bacteriocinogenic lactic acid bacteria (LAB) strains.
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.
