Cultures and culture filtrates of 129 Listeria innocua strains were examined for inhibitory activity against 18 strains of Listeria monocytogenes. Of the strains examined, 114 (88.4%) cultures and 126 (97.7%) culture filtrates had an inhibitory activity against strains of L. monocytogenes and most filtrates were sensitive to trypsin treatment. The authors concluded that most L. innocua strains produce a trypsin sensitive bacteriocin-like substance against L. monocytogenes.
