The Sundsvall bridge is being consumed by iron eating bacteria

Micans has discovered that the load bearing sheet pile is corroding much faster than anticipated. This is due to so called microbial corrosion. The steel has been attacked by iron-oxidizing bacteria belonging to the family Gallionellaceae together with sulphate-reducing bacteria. Micans' researchers have been experts on the bacterial family Gallionellaceae and on sulphate-reducing bacteria for a long time.

The discovery attracted great interest in media and Micans is now involved in a research project that will investigate how the bacterial attack can be limited or stopped.
