Abstract excerpt
A collection of Listeria monocytogenes isolates from various food products, food processing environments and clinical sources (n = 153) were evaluated for their tolerance to acetic, lactic and propionic acids. A large variation in tolerance was observed amongst isolates under mildly acidic conditions (pH 5.3) for acetic (5-20 mM undissociated acid) and propionic acid (2-10 mM undissociated acid) but there was...
