Lb. curvatus MBSa2 and MBSa3 isolated from
Italian type salami samples produce two bacteriocins (sakacin P
and sakacin X) with high stability (heat, pH and NaCl) and
remarkable activities against L. monocytogenes. The semi-purified
bacteriocins extracted from cultures of Lb. curvatus MBSa2 and
applied to the batter for salami production caused about 2 log CFU/
g count reduction in the final product when compared to salami
without addition of bacteriocins, suggesting that application of
these bacteriocins can be an additional measure to improving the
safety of these ready-to-eat products with regards to
L. monocytogenes.
