w and even before to our knowledge of the existence of microorganisms. The evolution of various subfields of microbiology over the past two centuries, as well as the contributions of pioneers in the basic and applied sciences, clearly demonstrated the importance of bacterial cultures for human health and nutrition. The scientific foundations of food microbiology, bio-preservation, probiotics, and other beneficial properties of microorganisms have been studied and arguments for their applications have been developed.Pediococcus spp., a member of LAB, has been shown to be effective in the production of antimicrobial peptides (bacteriocins) with applications in the food and health industries. Numerous studies have been published on the production of bacteriocins, their use in biopreservation processes, and more recently, their use in human and veterinary medicine (
