Abstract

The stagnant water conditions for a long time caused a thick and heterogen biofilm formation on the

surfaces. Due to the impact of consortium of different bacterial groups in the biofilm, the paint layer

was damaged locally, and steel was corroded in these areas. Bacteria of the sulfur-, iron-, and

manganese-cycles played a major role in this phenomenon.
