Knockout of three-component regulatory systems reveals that the apparently constitutive plantaricin-production phenotype shown by Lactobacillus plantarum on solid medium is regulated via quorum sensing.

Abstract excerpt

It has been found that many bacteriocins from lactic acid bacteria (LAB) are only produced in broth cultures when specific growth conditions are achieved and a dedicated three-component regulatory system, involved in a quorum sensing (QS) mechanism, is switched on. Surprisingly, bacteriocin production in LAB occurs in an apparently constitutive manner on solid media. This study addresses the question of...
