  1. 1. Partitioning of Drugs and Lignin Precursor Models into Artificial Membranes

    Författare :Elisabet Boija; Gunnar Johansson; Per Lundahl; Christine Lagerquist Hägglund; Marja-Liisa Riekkola; Uppsala universitet; []
    Nyckelord :Biochemistry; Bilayer disk; Capillary electrophoresis; Detergent; Drug; Electrostatic interaction; Hydrophobic interaction; Immobilized liposome chromatography; Lignin; Lignin precursor model; Liposome; Membrane model; Octanol water partitioning; Partitioning; Phospholipid; Phospholipid bilayer; Sterol; Biokemi;

    Sammanfattning : The main aim of this thesis was to characterize membrane-solute interactions using artificial membranes in immobilized liposome chromatography or capillary electrophoresis. The partitioning of a solute into a cell membrane is an essential step in diffusion across the membrane. LÄS MER

  3. 2. 13C-Enriched Dehydrogenation Polymers Used for Studying Light-Induced Yellowing of Lignocellulosic Materials

    Författare :Jim Parkås; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lignin model compounds; differentiating xylem; yellowing; Picea abies; 13C NMR spectroscopy; lignin; DHP; 13C-enrichment; solid state; spruce;

    Sammanfattning : This study deals with the use of selectively 13C-enriched dehydrogenation polymers (DHPs) as models of lignin in lignocellulosic materials for elucidating the reaction pathways involved in light-induced yellowing. Methods for the synthesis of coniferin, a precursor to lignin and DHP, selectively 13C-enriched in the aromatic ring (positions 1, 3, 4, and 5) have been developed. LÄS MER

  4. 3. Valorization of low-value lignocellulosic side-streams

    Författare :Daria Lebedeva; Joseph S. M. Samec; Emiel J.M. Hensen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lignocellulose; lignin; hemicellulose; hydrodeoxygenation; zeolites; furfural; catalysis; cycloaddition; biomass fractionation; pulping; Organic Chemistry; organisk kemi;

    Sammanfattning : The development of novel pathways for valorizing low-value streams from pulp, forest, and agricultural industries is crucial for realizing a circular bioeconomy and addressing the needs of both platform chemicals and fuels. Utilizing hemicellulose and lignin as biomass-derived feedstocks facilitates the production of sustainable liquid hydrocarbons, with catalytic hydrodeoxygenation being a key process. LÄS MER

  5. 4. A study of the traits associated with the biocontrol activity of Phlebiopsis gigantea

    Författare :Anthony Christian Mgbeahuruike; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Phlebiopsis gigantea has routinely been used for the biocontrol of the conifer pathogen, Heterobasidion annosum s.l. but the mechanism for the biocontrol action has not been properly understood. In the present work, 64 isolates of P. LÄS MER
