1st Minisymposium of the RTG1708:
"Stress Induced Metabolic Pathways"

The first Minisymposium organised by the RTG1708 will focus on "Stress Induced Metabolic Pathways" and will take place in Tübingen at the historical Alte Aula lecture hall of the University of Tübingen between July 24-25, 2017.

The general interest of the research training group 1708 "Molecular principles of bacterial survival strategies" is the maintenance of viability of bacteria in diverse environments. While normal growth by bacteria occurs under optimal conditions, in many habitats they are exposed to antagonistic conditions. We are interested in metabolic pathways that allow bacteria to withstand such stress conditions.

Renowned international speakers such as Erhard Bremer (University of Marburg), Tobias Erb (Max Planck Institute for Terrestrial Microbiology, Marburg), Julia Fritz-Steuber (University of Hohenheim), Marta Mendes (IBMC, University of Porto), Gary Sawers (University of Halle) and Greg Somerville (University of Lincoln-Nebraska) as well as the Ph.D students of the RTG1708 will give the participants an insight in their current findings.

More information regarding the Minisymposium on "Stress induce metabolic pathways" can be found hier.

Tübinger Fenster für Forschung 2017

This year the University of Tübingen organises once more the "Tübinger Fenster für Forschung" (TÜFFF). This event is directed to the general public to show more about the Tübinger research community. Different departments, institutions and working groups belonging to the University will give information about their research topics either in presentations, guided tours, roadshows or practical activities.

In this year's edition, the RTG1708 will again present itself to the public by uncommon ways. We aim to give an insight in the microbiologic world in a show-jumping course "A world without bacteria? Impossible!" mainly focused (but not only) on the smallest ones.
Among other activities there will be olfactory-tests, disinfection-test, bacterial art, microscope viewing to actively learn about microbiology. Several of our graduates are looking forward to welcome the interested guests, let them discover and answer their questions, do not miss it out!!

The TÜFFF will take place on April 28th in the lecture hall at Morgenstelle 16. The diversified program starts at 17:00 and will last until 22:00

Graduiertenkolleg zur Bakterienforschung verlängert

Wie passen sich Bakterien an feindliche Umweltbedingungen an? ­ ‒ Weitere 4,5 Jahre für GRK „Molekulare Mechanismen bakterieller Überlebensstrategien“

Die Deutsche Forschungsgemeinschaft (DFG) hat ein weiteres Graduiertenkolleg an der Universität Tübingen verlängert. „Molekulare Mechanismen bakterieller Überlebensstrategien“ (Molecular Principles of Bacterial Survival Strategies, GRK 1708) wird ab Oktober für weitere 4,5 Jahre gefördert, wie die DFG mitteilte.

Das GRK wird am Interfakultären Institut für Mikrobiologie und Infektionsmedizin der Universität Tübingen (IMIT) koordiniert (Sprecher Professor Karl Forchhammer, Lehrstuhl für Mikrobiologie/Organismische Interaktionen) und umfasst 12 Arbeitsgruppen aus Instituten der Universität (IMIT, Pharmazie, Organische Chemie und Geomikrobiologie) sowie je eine Arbeitsgruppe des Max-Planck-Instituts für Entwicklungsbiologie Tübingen und des Mikrobiologischen Instituts der Universität Stuttgart.

Das Graduiertenkolleg befasst sich seit April 2012 mit der Fragestellung, wie sich Bakterien an Umweltbedingungen anpassen, die das Wachstum behindern oder die Zellen schädigen. Die Fähigkeit, unter solchen Bedingungen lebensfähig zu bleiben, ist eine Grundvoraussetzung für die Besiedlung vieler natürlicher Standorte sowie für die Ausbreitung von Krankheitserregern. Dieses übergeordnete Thema soll von 13 Doktorandinnen und Doktoranden sowie einem Postdoc aus verschiedenen Blickwinkeln und an Fallbeispielen erforscht werden und so zu neuen Einsichten in einen wichtigen Teil der Bakterienphysiologie führen.

Die Kollegiaten erhalten neben den Aufgaben in der Forschung ein strukturiertes Ausbildungsprogramm während der Promotion, das fachübergreifende Fähigkeiten fördert. Workshops unterstützen zudem die Vernetzung in der internationalen Forschungslandschaft.
