  1. 1. Lipase-Catalysed Lipid Modifications in Supercritical Carbon Dioxide

    Detta är en avhandling från Department of Food Technology, Lund University

    Författare :Helga Gunnlaugsdottir; Lunds universitet.; Lund University.; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; immobilisation support; enzymes; pressure; phase behaviour; flow rate; process parameters; supercritical carbon dioxide; Lipase; lipids; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : The production of ethyl esters (EE) from ethanol and cod-liver oil by an immobilised lipase in supercritical carbon dioxide (SCCO2) is described. This reaction results in a complex mixture of lipid components consisting of triglycerides, diglycerides, monoglycerides and ethyl esters. LÄS MER

  2. 2. Molecular development of a thermostable β-glucosidase for modification of natural products

    Detta är en avhandling från Department of Food Technology, Lund University

    Författare :Sami Khan; Lunds universitet.; Lund University.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermotoga neapolitana; TnBgl1A; Mutagenesis; Flavonoid; Quercetin; Immobilisation; Chaperones;

    Sammanfattning : Popular Abstract in English The gene encoding a β-glucosidase originating from the extreme thermophile Thermotoga neopolitana has been cloned and expressed in Escherichia coli. The aim was to produce a thermostable enzyme that could be used to remove sugar residues from glucosylated natural products classified as flavonoids by applying a method combining extraction in hot pressurized water with enzymatic hydrolysis.

  3. 3. Lipases as Biocatalysts in Organic Media. Influence of Enzyme Preparation and Reaction Conditions on Activity and Selectivity

    Detta är en avhandling från Mattias Persson Sölvegatan 39, kemicentrum, Lunds universitet

    Författare :Mattias Persson; Lunds universitet.; Lund University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Bioteknik; Biotechnology; water activity; temperature; enantioselectivity; immobilisation; organic solvents; lyophilisation; Lipases; Accurel EP-100; Biokemisk teknik; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The discovery that enzymes can function in organic solvents has broadened the scope of biocatalysis, making enzymes highly useful tools for organic chemists. The widespread use of enzymes as catalysts in organic solvents has, however, been limited by the low activity obtained for enzymes in organic solvents compared to aqueous solutions. LÄS MER

  4. 4. Protein Microarrays Based on Single Framework Recombinant Antibody Fragments (SINFABS) - Catcher and Carrier - A Crucial Combination

    Detta är en avhandling från Department of Immunotechnology, Lund University

    Författare :Cornelia Steinhauer; Lunds universitet.; Lund University.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; probe; coupling chemistry; solid support; stability; scFv; antibody microarray; protein microarray; Biotechnology; Bioteknik;

    Sammanfattning : Popular Abstract in Swedish ?DNA-mikromatriser eller genchips? är idag väletablerade verktyg inom biologisk forskning och klinisk diagnostik. Genmikromatriser kan exempelvis användas för att i mikroskala studera genetiska skillnader mellan sjuka och friska vävnader. LÄS MER

  5. 5. Engineering of staphylococcal surfaces for biotechnological applications

    Detta är en avhandling från Stockholm : Bioteknologi

    Författare :Henrik Wernérus; KTH.; [2002]
    Nyckelord :affibody; albumin binding protein; Bacterial surface display; cell immobilisation; bioremediation; combinatorial protein engineering; flow cytometry; Gram-positive; metal-binding; staphylococcal protein A; Staphylococcus carnosus; Staphylococcus xylo;

    Sammanfattning : The engineering of bacterial surfaces has in recent yearsattracted a lot of attention with applications in manydifferent areas of bioscience. Here we describe the use of twodifferent surface display systems for the gram-positivebacteria Staphylococcus carnosus and Staphylococcus xylosus invarious biotechnological applications. LÄS MER
