Parameter values from model fits to CTec3 progress curves shown in Fig. 2

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
