| Description |
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.
