Another great collaboration between the Den and the Bange Lab in Marburg. A long-standing question is how do polarly flagellated gammaproteobacteria spatially organize flagellar assembly? Here we finally describe how it works. Preprint on BioRxiv.


Svenja and Dorian looked into the lysis system of Shewanella phage LambdaSo. The found the major components, the holin, the endolysin, the spanin - but that was not sufficient as another small protein, Lcc6, encoded elsewhere on the phage genome, is also required. bioRxiv version is here.


About 6 years ago we started to isolate phages for Shewanella. Here is the latest offspring of this - great work by Nicole and collaborators: A rolling circle-replicating plasmid hijacks an inovirus to be transduced to other cells. Smallest and most simple phage satellite system so far. Now accepted for AEM.


The Mikrokumpel ('Microbuddy') by Lily has come alive (for example here, or contact us)! An introduction to bacteria (and that they are not all making you sick, but are mostly friends & helpers) for children between 3 and x, with some further information for older readers as well. All income will be donated to early science education and research programs for children.

Our Lab is part of the Institute for Microbiology and Molecular Biology at the Justus-Liebig-Universität Gießen, a lively city in the centre of Germany with Germany's highest student to resident ratio. We are located at the Interdisziplinäres Forschungszentrum (iFZ), a Research Centre for Biosystems, Land Use and Nutrition. Our lab is also part of the SynMikro at Philips University Marburg.


Flagellar motor of Shewanella putrefaciens

The bacterial flagellar motor is a highly intricate rotating molecular nanomachine. We are interested in the spatiotemporal regulation of flagellar assembly and the various aspects by which flagellar production and functions can be regulated. The cryotomographic image of the Shewanella putrefaciens polar flagella motor was kindly provided by the Beeby Lab.


cell polarity

Numerous fundamental cellular processes in cells (including bacteria) require tight spatiotemporal regulation and coordination. We explore the mechanisms by which bacteria achieve appropriate spatiotemporal organization in particular at the cell pole.

Shewanella oneidensis microcolony

Prokaryotic viruses are the most abundant biological entity on earth and affect their hosts in multiple ways ranging from the cellular to the ecological levels. We are interested in the various ways and mechanisms by which bacteria and their phages interact.
