1. 31. An analytical framework for studying transcriptional regulation

   Författare :Christoph Sebastian Börlin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; ChIP-exo; S. cerevisiae; transcriptional regulation;

   Sammanfattning : The state and behavior of any living cell is controlled by a complex interplay of different regulatory processes, with the regulation of transcription playing a major role. When a cell adapts to a new environment it often does that by modulating gene transcript levels, mainly through changes in transcription factor binding events. LÄS MER

3. 32. Lipid Turnover in Plants and Yeast, A Study of Storage Lipid Synthesis and Lipid-Based Signalling in Plants and Yeast

   Författare :Maria Gustavsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; turnover; plasma membrane; plant; PLA2; biosynthesis; S. cerevisiae; triacylglycerol;

   Sammanfattning : In this thesis, lipid biosynthesis is discussed focussing on the genes and enzymes involved in the final step of storage lipid synthesis, on the enzyme phospholipase A2, and on cell membrane lipid homeostasis. The investigation of lipid metabolism revealed that in Saccharomyces cerevisiae, there are four genes that are essential for the final step of storage lipid biosynthesis; ARE1, ARE2, DGA1, and LRO1.

4. 33. Biobased Adipic Acid - Challenges in Establishing a Cell Factory

   Författare :Emma Skoog; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 2-hexenedioic acid; enzyme engineering; 6-aminohex-2-enoic acid; S. cerevisiae; adipic acid pathway via lysine; cell factory; C. viswanathii; lignocellulose; biorefinery; tolerance; in silico docking; adipic acid;

   Sammanfattning : Growing concern regarding climate change calls for sustainable solutions to significantly reduce our dependency on non-renewable fossil-based raw materials. One potential solution is the development of biorefineries where biobased, renewable raw materials are converted into valuable products via enzymatic, chemical or microbial conversion. LÄS MER

5. 34. Osmoregulation at different stages of the yeast life cycle

   Författare :Cecilia Geijer; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stress signalling; osmoregulation; aquaporins; cerevisiae; germination; germination;

   Sammanfattning : The ability to adapt to changing and potentially harmful conditions in the surrounding environment is crucial for fitness and survival of all living cells; in particular unicellular organisms, since they are frequently exposed to stress factors such as heat, drought, nutritional starvation and toxic substances. The aim of this thesis is to determine how cells respond to osmotic and nutritional changes in the environment and how downstream targets of signalling cascades are regulated. LÄS MER

7. 35. Ethanol Production from Lignocellulosic Materials: Potential of Continuous Cultivation, Immobilisation, and Zygomycetous Fungi

   Författare :Ria Millati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuous cultivation; galactose; Rhizopus; xylose; Rhizomucor; S cerevisiae; Mucor; M indicus; glucose; immobilisation; detoxification; arabinose; mannose; overliming; ethanol; dilute-acid hydrolysate;

   Sammanfattning : This thesis deals with the production of bio-ethanol, a sustainable alternative to fossil fuels, from dilute-acid lignocellulosic hydrolysate in a continuous immobilised cell system and fermentation of the hydrolysate by a zygomycete organism, M. indicus. LÄS MER
