The former institute director, , changed to the University of Duisburg-Essen from 1st October 2014, where he became the head of the Chair of Aquatic Microbiology. He is now also a member of the board of Directors of the IWW, an annex-institute of the University. Rainer Meckenstock has been leading the IGOE for the last 11 years and was also heading a vibrant research group dealing with the anaerobic degradation of groundwater contaminants. The research of the Anaerobic Degradation group will be further continued within the other five research groups at IGOE.

Research Interests

Anaerobic degradation of aromatic hydrocarbons

Several anaerobic bacterial strains able to degrade aromatic (BTEX) and polycyclic aromatic hydrocarbons (PAH) with sulfate as electron acceptor were isolated with a novel cultivation method. At present, special focus is on anaerobic degradation of naphthalene and methylnaphthalene by sulfate-reducing bacteria. We could show that both compounds are degraded via the central intermediate 2-naphthoic acid (Annweiler 2000, Meckenstock 2000). The studies revealed that anaerobic degradation of PAH proceeds via a new metabolic pathway by reduction and cleavage of the bicyclic ringsystem to a cyclohexane ring structure and not via the benzoyl-CoA pathway (see Fig.1). In addition, the peripheral degradation pathway of 2-methylnaphthalene to 2-naphthoic acid is investigated which proceeds via an activation of the methyl group by addition of fumarate and subsequent b-oxidation. Here, the first three enzyme reactions have been measured in crude cell extracts (Safinowski 2004, see Fig.2). The first activation reaction in anaerobic naphthalene degradation has been identified as a methylation to 2-methylnaphthalene (Safinowski 2006). The further degradation proceeds via the 2-methylnaphthalene degradation pathway. A second focus of the group is on anaerobic benzene degradation. We enriched several new benzene-degrading cultures with sulphate and iron as electron acceptors. Interestingly, the responsible microorganisms belong to anaerobic Gram-positive Firmicutes which introduces a new phylum to the anaerobic aromatic hydrocarbon degraders (Kunapuli et al. 2007; Abu Laban et al. 2008). The cultures produce benzoate as major metabolite which suggests a carboxylation as the initial enzymatic reaction.

Microbial impact on the mineralogy of metal oxides

Apart from the soluble electron acceptors needed for aerobic or anaerobic degradation of BTEX it is stated that metal oxides play a role as terminal electron acceptors for anaerobic respiration. In the current project we investigate the significance of metal reduction for the overall contaminant degradation with respect to different iron oxide minerals. Another aspect is to investigate how bacteria channel electrons to the solid metal oxide surface. We developed a new hypothesis that ferric iron colloids can enhance microbial iron reduction and serve as electron shuttles. We could show that colloidal ferric hydroxides are reduced at very high rates comparable to complexed, dissolved iron.

Curriculum Vitae

  • Rainer Meckenstock (born 1964) studied biology at University of Konstanz, Germany 1985-1990. I finished with a thesis in the group of Prof. Winfried Boss on microbial sugar transport systems (molecular microbiology).
  • I did my PhD at the Swiss Federal Institute of Technology (ETH) in Zürich, Switzerland, with a thesis on biochemistry of light-harvesting complexes of phototrophic bacteria (1990-1993) in the Institute of Molecular Biology and Biophysics with Prof. Zuber.
  • During my post-doc at the Swiss Federal Institute of Environmental Science andTechnology (EAWAG) in the group of Dr. van der Meer in Dübendorf, Switzerland, I developed molecular methods to monitor trichlorobenzene-degrading microorganisms and their degradation activities in the environment (PCR, RT/PCR, in situ hybridisation) (1993-1995).
  • I changed to the investigation of anaerobic degradation of aromatic hydrocarbons in the Microbial Ecology Group of Prof. Bernhard Schink, University of Konstanz, Germany, in 1996.
  • Here, I isolated novel anaerobic BTEX and PAH-degrading organisms and studied the degradation pathways. A new method to study microbial activities in the environment with analysis of stable isotope fractionation was developed.
  • Since 2000 I changed to the Center of Applied Geosciences at the University of Tübingen, Germany, and set up a Geomicrobiology group within the Chair of Environmental Mineralogy (Prof. Stefan Haderlein).
  • Research topics were the anaerobic degradation of mono- and polycyclic aromatic hydrocarbons (BTEX, PAH), isotope fractionation as a means to monitor biodegradation in contaminated groundwaters, limitations of natural attentuation, and the reduction of iron minerals as electron acceptor.
  • Since July 2003, I became the director of the Institute of Hydrology at GSF which changed its name to Institute of Groundwater Ecology with the beginning of 2004.
  • Since 2004, I belong to the Steering Committee (ständiger Ausschuss des WTR) of the HelmholtzZentrum München. I was chairman of the Steering Committee in 2008/2009
