Table 5.
Kinetic parameters for CelA tested on DACS in the presence and absence of Tween 20, Tween 80 and BSA. The model was fit to each progress curve shown in Fig. 4 by varying k i and KL. Values shown are best fit values and either their associated standard deviations or 95% confidence intervals.
| Additive | k s (h−1) | KL (g/L) | k i (×10−2 h−1) | t1/2 (h) | t1/2 95% CI (h) |
|---|---|---|---|---|---|
| None | 55a | 1.6 ± 0.3 | 3.4 | 21 | 16–25 |
| Tween 20 | 55a | 1.9 ± 0.2 | 2.1 | 33b | 28–39 |
| Tween 80 | 55a | 2.3 ± 0.2 | 2.3 | 31b | 27–35 |
| BSA | 55a | 2.1 ± 0.5 | 3.0 | 23 | 18–29 |
aValue was fixed while estimating values for remaining parameters.
bValue is significantly different than control tested in absence of additive (Student’s T-test, p < 0.05).
