Metabolic dynamics of Desulfovibrio vulgaris biofilm grown on a steel surface.

In this study, a comparative metabolomics approach combining gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) was applied first between planktonic cells and biofilms and then between pure cultures and biofilms of Desulfovibrio vulgaris. The results revealed that the overall metabolic level of the biofilm cells… (More)
