The antimicrobial activity of strains of Lactobacillus against bacterial pathogens includes the production of
bacteriocins, lactic acid and hydrogen peroxide (Servin, 2004).
Spanish scientists applied the
bacteriocins nisin, enterocins A and B, and sakacin K to cooked and dry cured ham that had been spiked with L.

Albusin B, a class III
bacteriocin produced by Ruminococcus albus, is a 32-kDa protein with relatively hydrophilic content that has moderate specificity against some ruminal bacterial species.
This antimicrobial activity is described by the synthesis of molecules such as organic acids, hydrogen peroxide, carbon dioxide, diacetyl and
bacteriocins [41].

Deraz et al., [32] reported, antibacterial activity of
bacteriocins is influenced via the following aspects:
bacteriocin concentration and purification degree, physiological condition of the indicator bacteria (e.g.
Bacteriocins obtained from LAB are antagonistic to other bacteria, most commonly to Gram-positive group (Cleveland et al.,2001).
