Inhibition-zone diameters, minimal inhibitory concentrations (MIC) and minimal bactericidal concentrations (MBC) of Moroccan seaweed essential oils (EOs).
| Treatments | Inhibition Zone (mm) | MIC (μg mL−1) | MBC (μg mL−1) |
|---|---|---|---|
| C. tamariscifolia | 46.3 ± 0.6 *** | 7.81 | 15.62 |
| S. muticum | 32.3 ± 0.6 *** | 62.5 | 125 |
| U. lactuca | n.a | n.a | n.a |
| CuSO4 | 45.3 ± 0.6 *** | 3.12 | 3.12 |
| DMSO | n.a | n.a | n.a |
Each value representing mean ± SD of six replicates, *** p < 0.001 indicates significant differences compared with DMSO, n.a not active.
