Daniel Jensen from Aarhus University will do a masters in our lab. The Masters will be under my supervision and that of Lars Ottosen. At SDU, Daniel will work on electrosynthesis and production of valuable chemicals from renewable resources.
Daniel has a BSc from the Department of Bioscience at Aarhus University, where he studied motility in cable bacteria. A year ago Daniel started a Master in Bioengineering at the Department of Engineering at Aarhus University.
Daniel, welcome to our SDU team!
On November 23rd, I gave an invited talk for the graduate schools of Microbiology at the Max Planck Institute of Terrestrial Microbiology, the Philips University Marburg and the University of Tuebingen.
It was an excellent meeting covering diverse aspects of microbiology, especially structural and molecular microbiology. It was wonderful to be once again in Marburg.
Here is the flyer for the meeting where you can see the line up of speakers selected by the students for the students: Neu Flyer Spotlight 03.11.2017
We discovered that Baltic Sea consortia rich in Geobacter and Methanosarcina carried out syntrophic acetate oxidation (SAO) mediated by conductive particles.
It’s a really exciting finding not only because it is of importance to our understanding of the iron the methane cycles but also because:
- it raises questions how anthropogenic discharge of conductive particles (from agriculture, forestry etc) affects methane emissions
- it can explain the presence of electrogens like Geobacter in the methanogenic zone
- it can explain isotope ratios characteristic of CO2 reductive methanogenesis in deep sediment layers where Methanosarcina (an acetoclastic methanogen) is abundant
- it is the first detailed description of a conductive particle-mediated SAO in consortia from sediments
- it is the first NanoSIMS description of a Geobacter-Methanosarcina consortium
We enjoyed doing the work and hope the scientific community will receive it with excitement.
On the 9th of October Amelia gave a talk about syntrophic acetate oxidation at the Survival Artist workshop in Marburg.
The list of speakers was incredible for anyone interested in interspecies interactions and not only.

Very thankful to Andreas Brune for the invite. Hoping to get more opportunities for collaborations and discussion with scientists at MPI Marburg in the near future.
We were surprised to discover that Methanosarcina reduced mobile and toxic uranium (VI) to less mobile and less toxic uranium (IV).
For now, you can find a preprint of this paper on Biorxiv: Potential for Methanosarcina to contribute to uranium reduction during acetate-promoted groundwater bioremediation
Will keep you updated.
