ResumenThe use of biopreservation techniques is increasing due to the current demands of consumers. In the present work, the inhibitory capacity of the lactic acid bacterium (LAB) Lactobacillus plantarum d1322 isolated from fresh fish (Sparus aurata) in the South of Spain was investigated in comparison with Lactobacillus sakei CECT strain 4808, a well-known bacteriocin producer, against the pathogens Listeria onocytogenes, Salmonella enterica and Escherichia coli O157:H7. Results showed a growth inhibition of pathogens when using LAB cells and cell-free supernatant obtained from LAB growth. Proteinaceous nature of the inhibitory substances was corroborated, suggesting that the antibacterial substance/s produced by Lactobacillus plantarum d1322 may belong to the well-known group of bacteriocins. Further studies could reveal the sequence and composition of the molecule involved in such inhibition.
