Metal corrosion rate (g/m2 d) and metal corrosion inhibition efficiency (%) of the SCGS reactors at different concentrations (mM) and inoculated with enriched environmental sulfidogenic bacteria cultivated at high medium salinity of 5.49% NaCl in comparison to a blank reactor (un-inoculated with the sulfidogenic bacteria with high medium salinity) and a control reactor (inoculated with the sulfidogenic bacteria with high medium salinity).
| Cultivated Reactors | Metal Corrosion Rate (g/m2 d) | Metal Corrosion Inhibition Efficiency (%) |
|---|---|---|
| Blank | 0.682 ± 0.02 | 0.0 |
| Control | 0.326 ± 0.07 | 52.9 |
| 0.1 mM | 0.462 ± 0.1 | 32.3 |
| 0.5 mM | 0.175 ± 0.005 | 75.0 |
| 1.0 mM | 0.084 ± 0.007 | 88.2 |
| 5.0 mM | 0.042 ± 0.004 | 93.8 |
