Plantaricin bacteriocins: As safe alternative antimicrobial peptides in food preservation—A review

Abstract

AbstractMany peptides are excreted by gram‐positive (+) and gram‐negative (−) bacteria, possessing antimicrobial properties, called bacteriocins. Common bacterial species produce bacteriocins are called lactic acid bacteria. Nowadays, plantaricins are natural antimicrobial peptides produced byLactobacillus plantarumstrains have obtained special attention. TheL. plantarumand their bacteriocins have got great importance in different areas as food biopreservatives and/or starters in dairy products, meat products, and fish products also, were used for treating diseases caused by pathogenic bacteria that is, reducing symptoms of irritable bowel syndrome disease (IBS) and decreasing the number of colonies of pathogenic bacteria in the wound‐burning model in mice. Moreover, plantaricins have got a potent protective role against urinary tract infection (UTI). Although there are many studies on the types of bacteriocins and their purification and uses, such as Nisin and Pediocin, there have been no reports in the literature on the characterizations, production, and purification of plantaricins. The present review aims to describe plantaricins and some of their features and applications in general. Also mentioned are the most common methods of isolation and purification.
