Description: Dieses Projekt wird neue Metallophore mittels LC/MS-Methoden identifizieren und ihre vielfältigen Funktionen insbesondere in stickstofffixierenden Lebensgemeinschaften und mikrobiellen Redox-systemen untersuchen. Um natürliche Quellen von Molybdän, einem essentiellen Cofaktor für Nitrogenasen, auch in aquatischen Kulturen nachzuahmen, werden Bibliotheken synthetischer Chelatoren entwickelt. Deren Komplexe dienen als - Mo-Puffer - in Nährmedien indem sie die Verfügbarkeit von Molybdänspezies kontrollieren. Zur Modellierung des Redoxsystems mikrobieller Fe(II)-Oxidierer und Fe(III)-Reduzierer werden spezielle Liganden bzw. Metallkomplexe entwickelt.

Title: Sub project C05: Metallophores as Mediators for Metal Cycling: Development of Libraries for Metal Ion Buffering and as Redox Carriers as well as Profiling of Metallophores
Description: This project aims to identify novel metallophores based on recently developed LC/MS analytical techniques and to unravel their multiple functions particularly in nitrogen-fixing and microbial iron-cycling systems. To mimic natural sources of molybdenum, which is an essential cofactor of nitrogenases, we will develop libraries of synthetic chelating agents for this metal. The resulting complexes serve as - Mo-buffers - to control the availability of molybdenum species in aqueous cultures. To model redox shuttle systems in communities of Fe(II) oxidizers and Fe(III) reducers appropriate ligands as well as metal complexes will be developed.
