Investigador Responsable Otto Geiger, Ph.D.

The research group

By the time this Research Group joined the Nitrogen Fixation Research Center in 1999, the laboratory of Otto Geiger had discovered the phosphatidylcholine synthase pathway, which constitutes a major route for phosphatidylcholine (lecithine) formation in bacteria. This finding started a research line aimed to understand how molecules of the bacterial membrane or cell surface modify defense responses of eukaryotic hosts thus allowing long-lasting or permanent infections which can lead to symbiotic or pathogenic interactions with the host.
