| Strain | Halo of inhibition diam (mm)a |
|---|---|
| Mesophilic strains | |
| B. cereus CECT 131 | 16 ± 0.5 |
| B. cereus CECT 495 | 13 ± 1.0 |
| B. cereus CECT 4014 | 19 ± 0.5 |
| Psychrotrophic strains | |
| B. cereus LWL1 | 19 ± 0.5 |
| B. cereus LWL3 | 19 ± 0.5 |

Samples were tested by using the agar well diffusion assay and 5 μg per well. The diameter of the halo of inhibition includes the well diameter (8 mm). The values are averages ± standard deviations based on three independent experiments.
