21. Diazotrophy and diversity of benthic cyanobacteria in tropical coastal zones
Abstract : Discoveries in recent years have disclosed the importance of marine cyano-bacteria in the context of primary production and global nitrogen cycling. It is hypothesized here that microbial mats in tropical coastal habitats harbour a rich diversity of previously uncharacterized cyanobacteria and that benthic marine nitrogen fixation in coastal zones is substantial.

22. Regulation of nitrogen fixation in Rhodospirillum rubrum : Through proteomics and beyond
Abstract : Adaptability is one of the reasons for the success of bacteria, allowing them to survive in conditions where no other organisms would be able to thrive. Nitrogen deficiency, for example, can be a limiting factor for the growth of micro-organisms, as this element is an essential part of almost all types of biomolecules. READ MORE

23. Metabolic regulation of nitrogen fixation in Rhodospirillum rubrum
Abstract : Nitrogen, along with carbon, hydrogen and oxygen, is amongst the most abundant elements in all living cells. The capability to convert atmospheric dinitrogen to biologically usable nitrogen compounds is only found in some prokaryotes. READ MORE

24. Computational Studies of Metalloenzymes
Abstract : Enzymes are involved in most reactions in nature. They are important both for the understanding of biological life and for reactions of industrial interest, e.g. in the production of artificial fertilizers, the production of biomass or biofuels. READ MORE

25. Towards an understanding of diazocyte development and diazotrophy in the marine cyanobacterium Trichodesmium
Abstract : Trichodesmium is a filamentous cyanobacterium of great ecological significance as it contributes significantly to primary production in oceans through an efficient nitrogen fixation strategy, including a unique cell type, the diazocyte. The aim of this thesis was to generate a deeper understanding of the structural and molecular background related to the development of diazocytes and the maintenance of diazotrophy in Trichodesmium erythraeum IMS101.
