Bacteriocins are small ribosomal synthesized peptide molecules that confer antimicrobial activity on the non-producer strains. Class II bacteriocin known as Pediocin is a potential antimicrobial agent that inhibits various pathogenic bacteria. The antimicrobial efficiency study of Pediocin revealed that pure compound from of pediocin is effective for very less time. The extended or controlled release is a proficient method to increase the antibacterial activity of pediocin. Among the various methods, encapsulation strategies are the best methods to increase the slow release of the bacteriocin hence make them as a powerful alternative to existing antibiotics.

Bacteriocins are ribosomally synthesized antimicrobial peptides produced by bacteria. The majority of bacteriocins fall into two categories: lanthionine-containing peptides, i.e., lantibiotics (class I) and unmodified bacteriocins (class II). Nisin and paenibacillin (He, Yuan, Zhang, & Yousef, 2008) are examples of the lantibiotics, whereas pediocin and enterocin RM6 (Huang et al., 2013) are class II bacteriocins.

Bacteriocins refer to proteins or protein complexes that have antagonistic effects on bacteria closely related to the genetics of the producer organism. They are mainly divided into three classes.[1] Class I bacteriocins usually consist of 19-50 amino acids and pass through posttranslational modification to produce nonstandard amino acids. Class II bacteriocins contain small, thermally stable, unmodified peptides, which can be further subdivided into class IIa (pediocin-like bacteriocins), class IIb (two-peptides unmodified bacteriocins), class IIc (circular bacteriocins) and class IId. Class III bacteriocins are mainly composed of high molecular weight and heat-labile bacteriocins.[2,3]
