Air | Catalase | k s (h−1) | k i (× 10−3 h−1) | t1/2 (h) |
---|---|---|---|---|
Ambient | No catalase | 16.5 ± 1.5 | 17.7 ± 2.7 | 39 ± 6 |
Ambient | Catalase | 14.9 ± 1.2 | 9.3 ± 1.8a | 75 ± 15b |
N2 | No catalase | 11 ± 0.9a | 1.2 ± 2.1a | 582 ± 981a |
N2 | Catalase | 10.5 ± 0.6a | 0 ± 1.3a | n/aa |
The model was fitted to each progress curves shown in Fig. 2 by varying k s and k i. Values shown are best fit values and their associated standard deviations. Statistically significant differences relative to the ambient air and no catalase control, as determined using Student’s T test, are indicated
a P value < 0.01 relative to value of equivalent parameter measured under ambient air conditions without catalase
b P value < 0.05 relative to value of equivalent parameter measured under ambient air conditions without catalase
