    Sammanfattning : We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).

  3. 2. Structural studies of sugar binding proteins

    Författare :Sanjeewani Sooriyaarachchi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Binding proteins, which are themselves non-enzymatic, play an important role in enzymatic reactions as well as non-enzymatic processes by providing a binding platform for the specific recognition of particular molecules. For example, periplasmic binding proteins play a vital role in nutrient uptake in Gram-negative bacteria. LÄS MER

  4. 3. Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

    Författare :Sara Jonsdottir Glaser; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; sugar beet pulp; wheat bran; agricultural residue; biomass valorisation; fractionation; bio-based platform chemicals; HMF; levulinic acid; heterogeneous catalysis; whole-cell catalysis;

    Sammanfattning : The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products of farming can be repurposed as feedstock for biorefineries. LÄS MER

  5. 4. Used but not Sensed - The Paradox of D-xylose Metabolism in Saccharomyces cerevisiae

    Författare :Karen Ofuji Osiro; Teknisk mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; saccharomyces cerevisiae; sugar sensing signalling; D-Xylose; XR XDH; GFP biosensor; cAMP PKA; Snf3p Rgt2p; SNF1 Mig1p; flow cytometry;

    Sammanfattning : The realization that the extraction and combustion of fossil fuels is having serious effects on the environment and the climate, together with the ever-growing need for fuels, has led to the development of the concept of the biorefinery. Biorefineries are refineries in which fossil resources, such as oil, are replaced by renewable biomaterials to produce biofuels and biochemicals. LÄS MER

  7. 5. Molasses Purification and Valorisation : Towards a sustainable production of hydroxymethylfurfural

    Författare :Mikael Sjölin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar beet molasses; 5-hydroxymethylfurfural; membrane filtration; hydrolysis; dehydration; adsorption; purification; solvent regeneration;

    Sammanfattning : The industrial transition from petrochemical-based to a more sustainable and circular economy requires the utilisation of renewable biobased raw materials that do not compete with other important industries, such as the food sector, preferably wastes or low value by-products. 5-hydroxymethylfurfural (HMF) is a versatile platform chemical that has great potential for utilisation in various sectors in a future bioeconomy, as it can be produced from sugars.
