  3. 2. Chiral building blocks for synthesis of pine sawfly sex pheromones Enantioselective Lipase Catalysed Acylations and Esterifications of Primary Alcohols and Acids and Synthesis of the Sex Pheromone of the Pine Sawfly Microdiprion pallipes

    Författare :Ba-Vu Nguyen; KTH; []
    Nyckelord :lipase; Pseudomonas cepacia; Candida rugosa; enantioselective; enantiomeric ratio; primary 2-methylalcohol; substituted-methylcarboxylic acid; pine sawfly; Microdiprion pallipes; sex pheromone; 3; 7; 11-trimethyl-2-tridecanol; stereoisomer;

    Sammanfattning : This thesis describes the development of new methods for thepreparation of enantiomerically pure methyl branched alkylcompounds and their use as building blocks in the synthesis ofstereoisomerically pure pheromones of pine sawflies.The high regioselectivity, enantioselectivity and activityof lipases in organic solvent in conjunction withenvironmentally compatible reaction conditions have madelipase-catalysed synthesis an attractive alternative toconventional synthetic methods in organic chemistry.

  4. 3. Biocatalysis in Organic Media: Parameters Influencing Activity, Stability and Enantioselectivity

    Författare :David Costes; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : Biocatalysis in organic media offers very attractive methods to prepare fine chemicals. The biocatalyst performance regarding activity, stability and enantioselectivity will determine the viability of the bio-process. LÄS MER

  5. 4. Chemoenzymatic methods for the syntesis of pine sawfly sex peromones

    Författare :Helen Edlund; KTH; []
    Nyckelord :pheromone syntheses; pine sawfly; diprion pini; gilpinia pallida; kenetic resolution; water activity;

    Sammanfattning : This thesis describes the syntheses of pine sawfly sexpheromones via two synthetic routes. The preparation ofenantiomerically pure building blocks for these is alsodescribed.Lipase catalysed methods were developed for either theresolution or desymmetrisation of building blocks. LÄS MER

  7. 5. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas

    Författare :Betty Mbatia; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; by-products; value addition; EPA; DHA; PUFA; biogas;

    Sammanfattning : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.
