Considering the exposed facts, the aim of this study is to evaluate the
capability of two Lactobacillus strain, Lactobacillus plantarum PCS20 and
Lactobacillus delbrueckii DSM20074, chosen on the basis of their previously
demonstrated anti-microbial activity against several pathogens
(Santini et al., 2010; Savino et al., 2011), of being protective cultures
against Clostridium strains in ground meat used for fermented salami production
in order to reduce or eliminate the nitrite amount added to meat.
