| Characteristic | Value for A. vinosum straina: |
||
|---|---|---|---|
| Wild type | ΔdsrR | ΔdsrR+dsrR | |
| Sulfide oxidation rateb | 199.0 ± 18.2 | 205.3 ± 0.4 | 200.0 ± 16.8 |
| Sulfur globule formation rateb | 90.7 ± 0.6 | 90.7 ± 5.0 | 89.5 ± 2.1 |
| Sulfur oxidation rateb | 24.1 ± 0.3 | 2.9 ± 0.5 | 23.9 ± 0.65 |
| Growth yieldc | 8.8 ± 0.9 | 9.0 ± 0.9 | 8.9 ± 0.5 |
a
The results represent the means and standard deviations of three independent growth experiments. Initial sulfide concentration, 2 mM.
b
Oxidation and formation rates are given as nmol min−1 mg protein−1.
c
The growth yield is given as g protein mol sulfide−1.
