    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lignocellulose; 5-carbon; 6-carbon; Trametes versicolor; xylose reductase; xylitol dehydrogenase; xylulokinase; phenolics; levulinic acid; HMF; furfural; biodegrader; biocatalyst; pretreatment; xylanase; beta-glucosidase;

    Sammanfattning : Energy consumption has increased rapidly during the last century due to population growth and greater industrialization. Lignocellulosic-based biofuels are being developed as alternatives to fossil fuels. For many years the question of how 5-carbon sugars in biomass are utilized in nature has been a vexed one. LÄS MER

  3. 2. 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.
