Growth rates, NH3-dependent O2 consumption, [U-14C]acetylene incorporation, and AMO mRNA
| Straina | Growth rateb (n)c | O2 uptaked (n) | [14C] incorp.e (n) | AMO mRNAf (n) |
|---|---|---|---|---|
| Wild type | 100 (6) | 100 (5) | 100 (4) | 100 (12) |
| amoA1 mutants | 75.2 ± 10.0 (8) | 85.2 ± 5.76 (6) | 80.7 ± 10.7 (4) | 63 ± 14 (12) |
| amoA2 mutants | 96.9 ± 6.7 (10) | 104.0 ± 6.9 (14) | 92.4 ± 6.6 (4) | 97 ± 23 (12) |
a
amoA1 mutants include strains A141 and A1, and amoA2 mutants include strains A142 and A2.
b
Mean growth rate (hour−1) as a percentage of the wild-type activity ± 1 standard deviation. The rate was calculated from an exponential curve fit from growth curves monitored by OD600.
c
n is the number of replicates used to calculate the mean and variance.
d
Mean activity as a percentage of the wild-type activity ± 1 standard deviation.
e
Mean amount of [14C] incorporated into the 27-kDa peptide of AMO as a percentage of the wild-type amount ± 1 standard deviation.
f
Mean amount of amo mRNA as a percentage of the wild-type amo mRNA amount ± 1 standard deviation.
