Antimicrobial activity of Enterococcus faecalis against Listeria monocytogenes

Six strains of Enterococcus faecalis were tested for antimicrobial activity against Listeria monocytogenes. Using the agar spot test, E. faecalis NRIC 1143 and 1144 showed strong activity against all of five strains of L. monocytogenes tested. Antimicrobial activities of these strains were inhibited by some proteolytic enzymes.
