The antimicrobial activity of strains of Lactobacillus against bacterial pathogens includes the production of bacteriocins
, lactic acid and hydrogen peroxide (Servin, 2004).
If inhibition zone were found in the third well, the isolates were considered to be able to produce bacteriocin
like substances) (18).
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.
: mechanism of membrane insertion and pore formation.
Bemena LD, Mohamed LA, Fernandes AM, Lee BH (2014) Applications of bacteriocins
in food, livestock health and medicine.
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

. The standard strain ATCC 10556 of S.
Deraz et al.,  reported, antibacterial activity of bacteriocins
is influenced via the following aspects: bacteriocin
concentration and purification degree, physiological condition of the indicator bacteria (e.g.
obtained from LAB are antagonistic to other bacteria, most commonly to Gram-positive group (Cleveland et al.,2001).
