The Cyclic Peptide Cyclo-zp80r Controls Salmonella enterica and Listeria monocytogenes Replication in Non-Concentrated (NFC) Orange Juice: Antibacterial Effects and Mechanisms of Action

The market for non-concentrated (NFC) orange juice is increasing rapidly due to consumer demand for nutrients and flavor. However, it encounters challenges in microbial safety, particularly from Salmonella enterica and Listeria monocytogenes. This study aimed to exploit a bio-preservative for NFC orange juice. Results showed that the cyclic peptide cyclo-zp80r had good antibacterial activity, with minimum inhibitory concentration values of 2–8 μM against S. enterica and L. monocytogenes. It...
