    Sammanfattning : Biocatalysis has become a popular technique in organic synthesis due to high activity and selectivity of enzyme catalyzed reactions. Enantioselectivity is a particularly attractive enzyme property, which is utilized for the production of enantiopure substances. LÄS MER

  4. 4. Lipases at Solid Surfaces ­ An Adsorption and Activity Study

    Detta är en avhandling från Food Technology, Lund University

    Författare :Kristin Wannerberger; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; surface wettability; solid surfaces; activity; adsorption; Ellipsometry; lipase; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Popular Abstract in Swedish Lipasadsorption till fasta ytor studerades med hjälp av in situ ellipsometri. Samtidigt mättes aktiviteten av det adsorberade lipaset in situ genom hydrolys av p-nitrofenylacetat. Adsorption mättes till metylerade kiseloxidytor med varierande grad av metylering samt till rent kiseloxid. LÄS MER
