Recently, in order to classify novel bacteriocins, Alvarez-Sieiro sate al. No advantage to the com- the many of the sequenced lantibiotic operons, as bination is seen when used to inhibit L. Recently, Verma et al. Immunity to Okereke, A. Cheeses are particularly vulnerable to the contamination of L.

Other studies also mention several limitations on the use of nisin in dairy products, due to its interaction with fat and other components in the food matrix Favaro et al.

Riadh HammamiUniversity of Ottawa, Canada. The main difficulty associated with this application is the lack of compatibility between the bacteriocin-producing strain and other cultures required in the fermentation of dairy foods. As a result, databases have been created to compile the information that can be used for the automated screening of bacteriocin gene clusters Blin et al. Consequently, several studies have also employed enterocin-producing enterococcus in food systems. preservstion

Smid Applied and environmental microbiology It is likely that more information regarding nisin safety exists, but is not available to the public. Bacteriocins can also be used to control adventitious non-starter flora, such as non-starter lactic acid bacteria NSLAB antimjcrobials cheese and wine, and in this way, contribute to the quality of the final product Oumer et al.
