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

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

    Abstract : 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. READ MORE

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

    Author : Camilla Rydström Lundin; Peter Brzezinski; Christoph von Ballmoos; Shelagh Ferguson-Miller; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 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

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

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

    Abstract : 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. READ MORE

  5. 5. 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.
