Bacteriocins, A Natural Antimicrobial Peptides For Food Preservation And Safety |

Control of Listeria monocytogenes in the rind of Taleggio, a surface-smear cheese, by a bacteriocin from Enterococcus faecium 7C5. In some countries, it is critical naturap make the distinction between bacteriocins and antibi- Bacteriocins are commonly divided into three or otics.

Proteolysis in cheese-making process may also affect the activity of nisin and limit its antimicrobial efficacy. Showing of references.
