The amount of binase protein released from zeolite samples into MQ-water and catalytic activity of the released enzyme.
| Zeolite sample | Released proteina/catalytic activityb, % | ||
|---|---|---|---|
| Time of incubation, h | 2 | 4 | 6 |
| Chabazite | 90.7 ± 0.7/147 ± 24 | 93.1 ± 1.0/133 ± 18 | 100 ± 0.4/nc |
| Clinoptilolite | 98.0 ± 0.9/115 ± 17 | 100 ± 0.5/97 ± 19 | 100 ± 0.6/n |
| Natrolite | 82.7 ± 0.5/57 ± 21 | 87.6 ± 0.3/112 ± 16 | 98.0 ± 0.4/n |
aThe amount of loaded binase was taken for 100%. bCatalytic activity RNase dissolved in MQ-water (1.588 ± 0.02 × 106 units/mg) was taken for 100%. cn – Not measured. Values are means ± SD. Experiments were performed in triplicate with five independent replications in each series.
