Bacteriocins: safe, natural antimicrobials for food preservation.
Listeria: A foodborne pathogen that knows how to survive.

The data suggest that pediocin PA-1 functions in a voltage-independent manner but requires a specific protein in the target membrane, while it is less effective with membranes derived from immune cells.
Functions and emerging applications of bacteriocins.
Functional analysis of the pediocin operon of Pediococcus acidilactici PAC1.0: PedB is the immunity protein and PedD is the precursor processing enzyme
It is concluded that both PedC and PedD are essential for pediocin transport, and that PedD is capable of processing prepediocin.

Carbon dioxide enhanced nisin-induced CF leakage, indicating that the synergistic action of CO2 and nisin occurs at the cytoplasmic membrane, consistent with a model where membrane fluidity plays a role in the efficiency of nisin action.
Effective control of Listeria monocytogenes by combination of nisin formulated and slowly released into a broth system.

There is an interest in the development of treatments using antimicrobials derived primarily from Lactobacillus spp.
Effect of triclosan on Salmonella typhimurium at different growth stages and in biofilms.
It is demonstrated that the tolerance of Salmonella towards triclosan in the biofilm was attributed to low diffusion through the extracellular matrix, while changes of gene expression might provide further resistance to tricrosan and to other antimicrobials.
ε‐Poly‐l‐lysine and nisin A act synergistically against Gram‐positive food‐borne pathogens Bacillus cereus and Listeria monocytogenes
Aims: To test ε‐poly‐l‐lysine and nisin A for possible synergistic activity against selected food‐borne pathogens and food spoilage organisms.
