Microcin J25 Exhibits Inhibitory Activity Against Newport in Continuous Fermentation Model Mimicking Swine Colonic Conditions.

Microcin J25 (MccJ25), a 21-amino acid bacteriocin produced by (), is a potent inhibitor of Enterobacteriaceae, including pathogenic , , and . Its lasso structure makes it highly stable and therefore of interest as a possible antimicrobial agent in foods or as an alternative to antibiotics in livestock production. In the present study, we aimed to evaluate the inhibitory activity of MccJ25 against subsp.
