Oxidation of several phenolic and non-phenolic substrates.
| Substrates | Concentration [mM] | Wavelength [λmax] [nm] | Residual activity [%] ± SD |
|---|---|---|---|
| Guaiacol | 5.0 | 450 | 100 ± 6.3 |
| Catechol | 5.0 | 450 | 85.4 ± 4.1 |
| Tyrosine | 5.0 | 280 | NR |
| Caffeic acid | 5.0 | 420 | 24.3 ± 2.2 |
| Tannic Acid | 5.0 | 458 | 63.1 ± 9.4 |
| 8-Hydroquinolone | 5.0 | 248 | NR |
| Oxalic acid | 5.0 | 450 | 3.7 ± 8.4 |
| Phenol | 5.0 | 370 | NR |
| Gallic Acid | 5.0 | 450 | 13.7 ± 2.2 |
| K4[Fe(CN)6] | 5.0 | 420 | 7.54 ± 1.2 |
The oxidation of several substrates was determined with guaiacol oxidation set at 100%. The values shown represent the average from triplicate experiments. Error bars represent the standard deviation.
