Synergistic action of ε-polylysine and theaflavin-3,3′-digallate against Hafnia alvei in turbot preservation: Quorum sensing disruption and bacterial sensitization

Key Points

• Hafnia alvei levels decreased significantly due to the synergistic action of ε-polylysine and theaflavin-3,3′-digallate, indicating successful antibacterial efficacy.
• The primary outcome demonstrated a remarkable reduction in bacterial growth by nearly 50% within 72 hours, showcasing the treatment's potency.
• Assessment using quorum sensing disruption methods provided a detailed understanding of the antibacterial mechanisms involved in the treatment.
• Findings indicate that combining these agents could enhance preservation methods for turbot, but further studies are needed to confirm long-term effects.
