The purpose of this study was to investigate pre-selected pediococci for potential probiotic use in Iberian dry-fermented sausages. A total of twelve strains isolated from Iberian dry-fermented sausages and pig faeces were evaluated according to safety and functional characteristics including biogenic amines and d-lactic acid production, antibiotic susceptibility, cell adhesion and antimicrobial activity against food-borne pathogens. The strain P. acidilactici SP979 was able to establish itself and compete with enteropathogens such as Salmonella choleraesuis on the intestinal epithelium and an inhibition of such pathogenic bacteria as Listeria monocytogenes and Staphylococcus aureus in vitro. This strain was also considered safe to be used with regard to its void aminogenic potential, low d-lactic acid production and antibiotic resistance pattern; being identified as a potential probiotic meat starter culture suitable for manufacture of dry-fermented Iberian sausages.
