Summary

Lactic acid bacteria (LAB) produce bacteriocins which are ribosomally synthesized antimicrobial proteins or peptides directed against certain microorganism species. The application of bacteriocins as food preservatives is a promising biotechnological approach in food safety. In this chapter we have reviewed some of the research and published literature on bacteriocins produced by LAB. We have described the importance of LAB bacteriocins, with a focus on topics such as detection, classification, mechanisms of action, genetic organization, regulation and immunity. Further, we have reviewed the potential applications of LAB bacteriocins and discussed the monitoring and synergetic approaches used to improve food safety. Due to the abundance of literature on LAB bacteriocins and the availability of relevant reviews, we have lessened the scope of this review to studies published mainly during the past 10 years.
