Wir erforschen die Interaktionen zwischen Mikroorganismen und Kohlenhydraten.
Mikroben-Kohlenhydrat-Interaktionen (MiCarb) - AG Reintjes
Emmy Noether Forschungsgruppe (DFG)
Was untersucht die MiCarb-Gruppe?
Wie Bakterien Zucker verarbeiten
Bakterien sind kleine, aber m?chtige Zuckerabbauer. Sie brechen komplexe Zucker in ihre Bestandteile auf und beeinflussen so die ?kosysteme. Wir erforschen, wie sie das machen und welchen Einfluss das hat - von den Ozeanen bis zu unseren eigenen Verdauungssystemen.
Mit Hilfe von fluoreszierenden Substraten und innovativen Methoden wollen wir die Geheimnisse der mikrobiellen Zuckerabbau entdecken. Wir kombinieren Ans?tze aus der Molekular?kologie, Mikrobiologie und Glykobiologie, um die F?higkeiten dieser kleinen Superhelden zu verstehen.
