Effects of salicylate on β-galactosidase production by strains MC100 and PC161
| Strain | Miller units of β-galactosidase (±S.D.) | ||||
|---|---|---|---|---|---|
| 0 | 2mM Sal. | FI/FD | 5mM Sal. | FI/FD | |
| MC100 | 128.26 ± 7.12 | 146.66 ± 7.13 | FI 1.14* | 159.83 ± 5.84 | FI 1.25* |
| PC161 | 29.43 ± 3.54 | 25.28 ± 3.28 | FD 1.16* | 25.73 ± 1.90 | FD 1.14* |
Sal., salicylate; FI, fold increase compared with non-induced strain; FD, fold decrease compared with non-induced strain; S.D., standard deviation (n = 3–9).
Significant change (P < 0.05).
