ABSTRACT

Investigations were carried out to determine the corrosion effect of sulphur-reducing bacteria on mild and medium carbon steels. Specimens were exposed to anaerobic, aerobic and distilled water environments. The corrosion rates were evaluated at intervals of seven days using weight loss and electro-chemical methods for a period of forty two days. The specimens were also subjected to visual examination and the result indicated uniform corrosion in all the environments. In all the environments, mild steel was most corrosive (6.43x10- 4mpy) due to high rate of depassivation of the oxide film by the corrosion inducing agents. Also, medium carbon steel recorded the least corrosion rate (5.30x10-4mpy) due to low rate of depassivation of the oxide film by corrosion-inducing agents. An average potential of -0.93mV was observed for mild steel in anaerobic environment, -0.89mV in Aerobic, -0.77mV in control. While an average potential of -0.91mV, was recorded for medium carbon steel in anaerobic environment, - 0.84mV in aerobic, -0.74mV in control.Mild steel recorded the highest electrode-potential.
