Sixty-five strains of lactobacilli isolated from salami were tested for their antifungal activity in early and late phases of growth. Ten strains showed inhibitory activity in the early phase of growth towards moulds such as Aspergillus and Penicillium. The active compounds identified were phenyl-lactate and hydroxy-phenyl-lactate. All strains tested had activity in the late phase, after autolysis. The compounds released were peptidic and showed antifungal activity.
