  1. 6. Proteostasis in Bacillus subtilis : chaperones and stress-response mechanisms

    Författare :Judith Matavacas; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein homeostasis; Chaperones; DnaK; trigger factor; Spx; YjbH; Bacillus subtilis;

    Sammanfattning : The maintenance of protein homeostasis, also referred to as proteostasis, is essential for preserving the structural and functional stability of the proteome in living organisms. This involves the precise control of protein synthesis, folding, and degradation. LÄS MER

  3. 7. Bioprocess development for biochemical conversion of lignocellulose

    Författare :Ruifei Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulose; strain engineering; stress tolerance; kinetic modelling; high gravity; scale-up; biofuels; SSCF; process development; Saccharomyces cerevisiae;

    Sammanfattning : Due to its low environmental impact and high maturity of the fuel ethanol market, lignocellulosic ethanol is a promising option for reducing the carbon footprint in the transport sector. The characteristics of lignocellulosic feedstocks, such as varied sugar composition, low sugar density, low solubility, recalcitrance to enzymatic degradation, and inhibitors formed during thermochemical pretreatment, have so far limited the production process, and costs for conversion of lignocellulosic materials to ethanol are still high.

  4. 8. Structure determination of Methanocaldococcus jannaschii nucleoside kinase

    Författare :Linda Arnfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Methanocaldococcus jannaschii; Archaea; hyperthermophile; nucleoside kinase; ribokinase family; X-ray crystallography; differential scanning calorimetry; thermal stability;

    Sammanfattning : All organisms can be divided into the tree kingdoms of life: Archaea, Bacteria and Eukarya. Archaeal organisms are often found to exhibit, compared to human perspectives, extreme environments, such as high temperature, high salt and acidic habitats. Many archaeal species are hyperthermophiles, i.e. LÄS MER

  5. 9. Improving Stress Tolerance in Industrial Saccharomyces cerevisiae Strains for Ethanol Production from Lignocellulosic Biomass

    Författare :Valeria Wallace; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; lignocellulose; ethanol; inhibitors; temperature; stress tolerance;

    Sammanfattning : The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors.
