  2. 1. The Role of Hexose Transport on Glycolytic Flux and Glucose Induced Responses in Saccharomyces cerevisiae

    Author : Karin Elbing; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glucose signaling; metabolic control; Snf1; glycolysis; Mig1; Hexose transport; Yeast; Saccharomyces cerevisiae;

    Abstract : 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. READ MORE

  4. 2. The molecular basis for substrate recognition and gating in sugar transporters

    Author : Sarah McComas; David Drew; Philip Biggin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane transport; sugar transporter; simulations; lipids; antimalarial drugs; biokemi; Biochemistry;

    Abstract : 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. READ MORE

  5. 3. Improving initial xylose metabolism in recombinant Saccharomyces cerevisiae

    Author : Márk Gárdonyi; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; xylose isomerase; xylose transport; xylose fermentation; Saccharomyces cerevisiae; metabolic engineering;

    Abstract : 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. READ MORE

  6. 4. Analysis and engineering of central metabolism in Clostridium thermocellum

    Author : Teun Kuil; Antonius J. A. van Maris; Ruud Weusthuis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; biofuels; ethanol; atypical glycolysis; pyrophosphate; phosphofructokinase; thermodynamic driving force; redox cofactor balancing; amino acid secretion; chaotropicity; hexose utilization; laboratory evolution; metabolic engineering; Biotechnology; Bioteknologi;

    Abstract : 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. READ MORE

  7. 5. Design of kinetic models for assessment of critical aspects in bioprocess development : A case study of biohydrogen

    Author : Johanna Björkmalm; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic models; biohydrogen; Caldicellulosiruptor; substrate; diauxic; inhibition; osmotolerance;

    Abstract : 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. READ MORE
