Bacteriocins are ribosomally synthesized bacterial antimicrobial
peptides [1]. Many food pathogens as well as opportunistic
bacteria that cause food spoilage are inhibited by these peptides.
Particularly, bacteriocins from lactic acid bacteria (LAB) are being
employed as antimicrobial agents for foods.In this regard, nisin
and pediocin PA-1 were approved as food biopreservatives [2].
Actually, nisin was approved as food antimicrobial agent in 1969
by FAO/WHO Expert Committee on Food Additives and its use is
permitted in over 50 countries nowadays
