1. The Role of Hexose Transport on Glycolytic Flux and Glucose Induced Responses in Saccharomyces cerevisiae
Sammanfattning : In the yeast Saccharomyces cerevisiae, glucose is primarily fermented rather than respired. Only in cultivation modes such as chemostats or fed-batches, where the external glucose is kept low, a fully respiratory catabolism is observed. LÄS MER
2. The molecular basis for substrate recognition and gating in sugar transporters
Sammanfattning : Sugar is a vital sustenance for most forms of life. For a cell to take up sugar, specialized transport proteins embedded into the membrane bilayer known as sugar porters, are required. LÄS MER
3. Improving initial xylose metabolism in recombinant Saccharomyces cerevisiae
Sammanfattning : The aim of the thesis is to improve the initial steps of xylose metabolism in recombinant Saccharomyces cerevisiae. S. cerevisiae takes up xylose of poor affinity by means of hexose transporters. Metabolic control analysis was used to investigate whether the low xylose utilisation rate is due to inefficient transport. LÄS MER
4. Analysis and engineering of central metabolism in Clostridium thermocellum
Sammanfattning : To mitigate climate change, greenhouse gas emissions must be reduced to net-zero in 2050 requiring a drastic transition in today´s energy sector. To achieve this goal, the use of biofuels produced from lignocellulosic feedstocks, including agricultural and forestry residues, is expected to play an important role. LÄS MER
5. Design of kinetic models for assessment of critical aspects in bioprocess development : A case study of biohydrogen
Sammanfattning : The world faces major climate challenges and extensive efforts need to be taken to combat this issue. Replacing fossil-derived fuels and chemicals with renewables are one important step on the way. Hydrogen has a great potential as a renewable energy carrier for the transport sector and as a green chemical for the industry. LÄS MER
