Research

Key to the central role of sulfate-reducing bacteria (SRB) in the mineralization of organic matter in marine sediments is not only their capacity for complete oxidation but also their broad nutritional versatility. Therefore, SRB can be expected to significantly contribute to the compositional shaping of organic matter in marine sediments. We use targeted and non-targeted metabolite analysis to test the hypothesis that metabolism of Desulfobacteraceae exerts a key control on organic matter composition in marine sediments. Comparison of targeted metabolomes assessed upon cultivation with different substrates aims at providing detailed insights into the influence of an important environmental parameter, i.e. the availability of a specific substrate. We are characterizing exo- and endometabolomes under different substrate conditions using an array of analytical techniques including GC- and LC‑MS as well as ultrahigh-resolution Fourier transform-ion cyclotron resonance mass spectrometry.
