Résumé

A Lactobacillus sake strain LKE5 and four strains of Carnobacterium piscicola were evaluated as biopreservation cultures to control the growth of Listeria monocytogenes on vacuum-packed, cold-smoked salmon stored at 5 °C. All five strains were antilisterial as live cultures in an agar diffusion assay. The growth of L. monocytogenes was strongly repressed on cold-smoked salmon in the presence of C. piscicola A9b and A10a, respectively. The initial cell numbers of L. monocytogenes that were found on Oxford plates incubated at 25 °C reached low maximum cell counts of 10,000 and 2000 after 14 and 20 days of storage in mixed culture with C. piscicola A9b and A10a.
