  1. 1. Engineering Saccharomyces cerevisiae for mixed-sugar fermentation

    Författare :Rosa Garcia Sanchez; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; evolutionary engineering; promoter; mixed-sugar utilization; galactose; arabinose; xylose; Saccharomyces cerevisiae; fermentation; ethanol; phosphoglucomutase;

    Sammanfattning : Efficient fermentation of all the monomeric sugars derived from lignocellulose is crucial to increase the economy of bioethanol production, since they can account for a considerable fraction of the fermentable sugars in the raw material. This thesis describes the engineering of Saccharomyces cerevisiae strains for improved xylose, galactose and/or arabinose utilization. LÄS MER

  2. 2. Modulators of Saccharomyces cerevisiae cytochrome c oxidase : Implications for the regulation of mitochondrial respiration

    Författare :Camilla Rydström Lundin; Peter Brzezinski; Christoph von Ballmoos; Shelagh Ferguson-Miller; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; cytochrome c; OXPHOS; membrane protein; kinetics; ligand-binding; electron transfer; Rcf1; respiratory supercomplexes; Saccharomyces cerevisiae; Biochemistry; biokemi;

    Sammanfattning : Oxidative phosphorylation in mitochondria is performed by enzyme complexes and electron carriers that reside in the inner membrane. It is now generally accepted that these respiratory enzyme complexes assemble into larger so-called supercomplexes. However, it is presently not known why, under which conditions or how these supercomplexes form. LÄS MER

  3. 3. Nitrogen and Redox Metabolism in Saccharomyces cerevisiae

    Författare :Eva Albers; Chalmers University of Technology; []
    Nyckelord :Saccharomyces cerevisiae; glutamate; protein expression; anaerobic physiology; nitrogen metabolism; redox; serine;

    Sammanfattning : 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. LÄS MER

  4. 4. Improving initial xylose metabolism in recombinant Saccharomyces cerevisiae

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

    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

  5. 5. Industrial Systems Biology and Metabolic Engineering of Saccharomyces cerevisiae

    Författare :José Manuel Otero; Chalmers University of Technology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolic engineering; industrial systems biology; Saccharomyces cerevisiae;

    Sammanfattning : Saccharomyces cerevisiae is the most well characterized eukaryote, the preferred microbial cell factoryfor the largest industrial biotechnology product (bioethanol), and a robust commercially compatible scaffold to be exploited for diverse chemical production. Succinic acid is a highly sought after added-value chemical whichis not overproduced in native S. LÄS MER
