  1. 1. Tools in biocatalysis : enzyme immobilisation on silica and synthesis of enantiopure amines

    Författare :Karim Engelmark Cassimjee; Per Berglund; Torkel Berglund; Torbjörn Gräslund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents two techniques in the field of biocatalysis: An enzyme immobilisation method based on the His6-tag for attachment on modified silica oxide beads, and it’s employment in aqueous and organic medium for synthesis applications. The method functions as a one step extraction and immobilisation protocol. LÄS MER

  3. 2. Stress Related Emissions of Norway Spruce Plants

    Författare :Marie Pettersson; Anna-Karin Borg-Karlson; Torkel Berglund; Åsa Emmer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volatiles; terpenes; green leaf volatiles; stress response; nepetalactone; SPME; Picea abies; Hylobius abietis; Cinara pillicornis; Chemistry; Kemi;

    Sammanfattning : The interactions between plants and insects are mediated by volatile molecules. Plants respond to stress by biosynthesis of chemical substances which can deter invading insects or pathogens. Some of these substances are volatile and are emitted to the surroundings and may attract or repel insects. LÄS MER

  4. 3. Exploring glycoside hydrolase family 5 (GH5) enzymes

    Författare :Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []
