  2. 1. Nitrogen and Redox Metabolism in Saccharomyces cerevisiae

    Author : Eva Albers; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces cerevisiae; glutamate; protein expression; anaerobic physiology; nitrogen metabolism; redox; serine;

    Abstract : Anaerobic conversion of glucose to ethanol by the yeast Saccharomyces cerevisiae has been studied. Glycerol is formed as a by-product in order to maintain the overall redox balance. READ MORE

  4. 2. Efficient Conversion of Lignocellulose Hydrolysates- Yeast Tolerance and Redox Metabolism

    Author : Tobias Modig; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metabolism; Biokemi; metabolism; hyperosmotic stress; Biochemistry; S. cerevisiae; anaerobic growth; inhibitor tolerance; furfural; lignocellulose; HMF; Biotechnology; Bioteknik;

    Abstract : The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for ethanol production was investigated. An important problem for the successful conversion of these hydrolysates is that they often are inhibitory. 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. Engineering xylose and arabinose metabolism in recombinant Saccharomyces cerevisiae

    Author : Kaisa Karhumaa; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virologi; bakteriologi; mycology; Mikrobiologi; bacteriology; Saccharomyces cerevisiae ; arabinose; xylose; fermentation; lignocellulose; yeast; mykologi; Biochemical technology; Biokemisk teknik; virology; Microbiology; ethanol;

    Abstract : Utilization of all sugars in lignocellulose hydrolysates is a prerequisite for economically feasible bioethanol production. The yeast commonly used for industrial ethanol production, Saccharomyces cerevisiae, is naturally unable to utilize pentose sugars xylose and arabinose, which constitute a large fraction of many lignocellulosic materials.

  7. 5. Engineering Lipid Metabolism for Production of Oleochemicals in Saccharomyces cerevisiae

    Author : Paulo Teixeira; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleochemicals; lipid homeostasis; Saccharomyces cerevisiae< i>; lipid metabolism;

    Abstract : Oleochemicals are chemicals usually derived from plant oils or animal fat. Large use of plant oil derivatives as replacements for petroleum-derived chemicals brings sustainability issues from extensive cultivation of oil plants in restricted regions. READ MORE
