Abstract
Abstract Bacteriocin compositions comprising lanthionine containing bacteriocins and non-bactericidal agents. When the bacteriocin compositions are combined with a suitable carrier with each component present in sufficient quantities such that the composition is effective against Gram negative bacteria in addition to Gram positive bacteria, they become enhanced, rapid acting, broad range bactericides suitable for a variety of applications.
