Disc diffusion of isolated compounds against Bacillus sp.
| Bacillus sp. | Inhibition Zone (mm) ± SD | |||
|---|---|---|---|---|
| AA | β-A | CHX | DMSO | |
| B. cereus ATCC33019 | 8.00 ± 0.00 | 9.31 ± 0.50 | 11.4 ± 0.31 | n.a |
| B. subtilis ATCC6633 | 8.81 ± 0.24 | 8.51 ± 0.50 | 11.1 ± 0.10 | n.a |
| B. pumilus ATCC14884 | 7.81 ± 0.22 | 8.51 ± 0.50 | 11.1 ± 0.10 | n.a |
| B. megaterium ATCC14581 | 7.21 ± 0.21 | 8.15 ± 0.50 | 11.6 ± 0.30 | n.a |
n.a: No activity. The diameter of the inhibition zones is in mm (including disc). Positive control (Chlorhexidine: CHX; 0.1%). Negative control (DMSO; 10%). Results were expressed as means ± standard deviation (SD); n = 2 × 3. AA: Asaronaldehyde, and β-A: β-asarone.
