Denaturing gradient gel electrophoresis (DGGE) and fluorescence in situ hybridisation (FISH) were
applied to biofilm and water samples collected from a number of North Sea seawater injection systems
and a laboratory mesocosm model system. The data were compared to determine common findings
and gross differences between locations with the ultimate aim of determining any correlation with the
occurrence of Microbiologically Influenced Corrosion (MIC). The results are discussed with regard to
the potential of using DGGE and FISH protocols to develop a common routine monitoring tool
applicable to the measurement of MIC mitigation controls.
