This paper presents the application of metabolomic techniques to determine the presence of microbial influenced corrosion (MIC). In a previous study, the extracellular metabolites expressed from pipe biofilm was identified by analysing the passing water. This investigation extends this work by successfully applying a chemometric statistical analysis to the extracellular metabolomic profile of a number of water samples to identify critical metabolomic biomarkers. The chemometric analysis was able to differentiate samples due to a reduction of carboxylic acids in samples exposed to bacteria believed to cause MIC.
► Analysis of bulk water using metabolomics provides information on pipe biofilm. ► Metabolomic profiling and chemometric analysis can differentiate biofilms. ► A reduction in carboxylic acids was evident in samples exposed to MIC bacteria.
