Abstract:
In the lactic acid bacterium Carnobacterium piscicola LV17B a peptide-pheromone dependent quorum-sensing mode is involved in the regulation of bacteriocin production. Bacteriocin CB2 was identified as an environmental signal that induces bacteriocin production. Here, we demonstrate that a second 24 amino acid peptide (CS) also induces bacteriocin production. Transcription activation of several carnobacteriocin operons is triggered by CB2 or CS via a two-component signal transduction system composed of CbnK and CbnR.
