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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Coiled coil cytoskeleton in cell architecture and osmotic stress response in Streptomyces

    Författare :Katsuya Fuchino; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coiled coil protein; Streptomyces coelicolor; polar growth; osmotic-stress response; turgor;

    Sammanfattning : Coiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. LÄS MER

  4. 3. Downstream functions of the Sty1 MAPK pathway in S. pombe

    Författare :Eva Asp; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; S.pombe; MAPK; Sty1; Mkp1; oxidative stress; translation; mRNA stability;

    Sammanfattning : MAP kinase pathways are involved in the response to environmental changes in eukaryotic cells regulating transcriptional and translational events. In S. LÄS MER

  5. 4. 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. 5. The Saccharomyces cerevisiae MAPKAP kinases Rck1 and Rck2 in stress responses

    Författare :Elizabeth Bilsland; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Saccharomyces cerevisiae protein kinases Rck1 and Rck2 (Radiation sensitivity Complementing Kinases) were originally cloned as suppressors of Schizosaccharomyces pombe checkpoint mutants. In Saccharomyces cerevisiae we found that overexpression of either kinase has the ability to depress sporulation in mec1 and rad24 mutant backgrounds. LÄS MER
