Colicin E1 has High Antimicrobial Activity against Listeria Monocytogenes in Culture and on Packaged Ham
Abstract
Colicins are gram-negative bacteriocins produced by, and effective against Escherichia coli and closely related species. This study evaluated the activity of a purified poreforming, Colicin E1 (ColE1) against L. monocytogenes in broth and on RTE product surfaces. Colicins were effective at reducing Listeria populations at doses as low as 0.1µg/mL in broth culture, and up to 5.5 log CFU/g on cured ham slices. Colicins may be an effective intervention for the control of Listeria in ready to eat meat products.
