Comparison of the specific rates of ferrous iron and tetrathionate oxidation by Acidithiobacillus sp. ATCC 33020, and conversion of these into specific rates of energy generation in unit time.
| Electron donor | Oxidation rate (mmol min−1 g protein−1) | Energy generation (J min−1 g protein−1) |
|---|---|---|
| Fe2+ | 7.9 ± 0.21 | 237 ± 6 |
| 0.21 ± 0.027 | 260 ± 33 |
