Corrosion and microfouling studies on copper were carried out in pond water and mixed culture of Pseudomonas sp., Vibrio sp. and Bacillus sp. The effect of biofilm in natural and mixed culture on corrosion of copper has been found out by various methods like weight loss, polarization and impedance measurement for an exposure period of 100 days. Less corrosion current and high resistance values were observed for copper in pond water biofilm and mixed culture biofilm. The nature of the corrosion products in the presence of biofilm has been identified by XRD analysis. XRD data show broad peaks obtained in the presence of natural biofilm, indicating that the films are made up of organic compounds. The results suggest that bacterial activity inhibits the corrosion of copper.
