1. Engineering cytosolic acetyl-CoA metabolism in Saccharomyces cerevisiae
Abstract : A Saccharomyces cerevisiae strain carrying deletions in all three pyruvate decarboxylase genes (also called Pdc negative yeast) represents a non-ethanol producing platform strain for biochemical production. However, it cannot grow on glucose as the sole carbon source due to the lack of cytosolic acetyl-CoA for lipid biosynthesis. READ MORE

2. Electron transport to nitrogenase in Rhodospirillum rubrum
Abstract : Biological nitrogen fixation is a key step in the global nitrogen cycle. In this process, dinitrogen in the air is converted to biologically accessible ammonia, which is further assimilated in to the biosphere. READ MORE

3. Ultrafast Structural and Electron Dynamics in Soft Matter Exposed to Intense X-ray Pulses
Abstract : Investigations of soft matter using ultrashort high intensity pulses have been made possible through the advent of X-ray free-electrons lasers. The last decade has seen the development of a new type of protein crystallography where femtosecond dynamics can be studied, and single particle imaging with atomic resolution is on the horizon.

4. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production
Abstract : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.

5. Quantum Chemical Cluster Modeling of Enzymatic Reactions
Abstract : The Quantum chemical cluster approach has been shown to be quite powerful and efficient in the modeling of enzyme active sites and reaction mechanisms. In this thesis, the reaction mechanisms of several enzymes have been investigated using the hybrid density functional B3LYP. READ MORE
