1. The Heterocysts of Nostoc punctiforme : From Proteomics to Energy Transfer
Abstract : The aim of this thesis is to provide a thorough characterization of the photosynthetic machinery from the heterocysts of Nostoc punctiforme strain ATCC 29133. In this thesis I describe the protocols I have optimized for the isolation of thylakoids from vegetative cells, the purification of heterocysts and the isolation of thylakoids from the purified heterocysts.

2. The Nostoc Symbiont of Lichens : Diversity, Specificity and Cellular Modifications
Abstract : Cyanobacteria belonging to the genus Nostoc have the capacity to form symbiotic associations with a wide range of organisms. Diversity, specificity and cellular modifications of the symbiosis between Nostoc and fungi in the formation of lichens were investigated in this thesis. READ MORE

3. Cyanobacterial Hydrogen Metabolism - Uptake Hydrogenase and Hydrogen Production by Nitrogenase in Filamentous Cyanobacteria
Abstract : Molecular hydrogen is a potential energy carrier for the future. Nitrogen-fixing cyanobacteria are a group of photosynthetic microorganisms with the inherent ability to produce molecular hydrogen via the enzyme complex nitrogenase. This hydrogen is not released, however, but is recaptured by the bacteria using an uptake hydrogenase. READ MORE

5. Maturation and Regulation of Cyanobacterial Hydrogenases
Abstract : Accelerated global warming plus an increasing need for energy is an equation not easily solved, thus new forms of sustainable energy production are urgently requested. In this context hydrogen production based on a cyanobacterial system offers an environmentally friendly alternative for energy capture and conversion. READ MORE
