Genetic Analysis with Random Amplified Polymorphic DNA of the Multiple Enterocin-Producing Enterococcus lactis 4CP3 Strain and Its Efficient Role in the Growth of Listeria monocytogenes in Raw Beef Meat

Table 1

Inhibitory spectrum of E. lactis 4CP3, CR4, CL, 5CP2, C15, and C23 strains against L. monocytogenes EGDe 107776.

Test strain	Diameter of inhibition zones (mm)
E. lactis 4CP3	12.00±1.0
E. lactis CR4	10.00±1.0
E. lactis CL	5.00±0.0
E. lactis 5CP2	5.00±0.0
E. lactis C15	0.00±0.0
E. lactis C23	0.00±0.0
PC	18.00±2.0
NC	0.00±0.0

Results are reported as means ± standard error of three replicates.: averages with different letters in the same column, for each diameter of inhibition zones, are significantly different (P<0.05). PC: positive control (Novobiocin 1 mg/ml) and NC: negative control (noninoculated MRS broth medium).
