  1. 21. Improving Productivity and Enzyme Stability Through Process Design: Lipase-catalysed Synthesis of Epoxides and Esters

    Författare :Anna Hagström; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Interest in sustainable development has increased throughout society during the past decades, and the chemical industry is no exception. The appeal for renewable raw materials has consequently increased and has paved the way for the implementation of industrial biotechnology. LÄS MER

  3. 22. Lipase catalysed synthesis of speciality chemicals: technical, economical & environmental aspects

    Författare :Pär Tufvesson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green Chemistry; surfactant; biocatalysis; enzymatic; epoxide;

    Sammanfattning : Most people agree that the total ecological impact of society has become more than this planet can endure. This is because we consume our resources (such as oil and water) faster than they can regenerate and because we release more substances into the environment than can be assimilated (e.g. CO2).

  4. 23. Chemo-enzymatic epoxidation: Activity and stability of Candida antarctica lipase B

    Författare :Ulrika Törnvall; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Growing concerns about climate change and depleting fossil feedstocks are driving a shift within the chemical industry from energy-intensive processes to more environmentally sound and sustainable processing using renewable feedstocks. One such process is the utilization of lipases for the chemo-enzymatic epoxidation of vegetable oils and fatty acids. LÄS MER

  5. 24. Oxidation of Ketones: A (Chemo-) Enzymatic Approach Using Oxygenases and Hydrolases

    Författare :Georgina Chávez; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross linked enzyme aggregates.; caprolactone; perhydrolase; Lipase B from Candida antarctica;

    Sammanfattning : Oxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage.

  7. 25. Automated behavioral phenotyping of inbred mouse strains and mouse models of Alzheimer disease

    Författare :Alina Codita; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Behavioral characterization of various mouse strains created as models for human diseases such as Alzheimer disease requires robust phenotyping methods. Previous work on inbred mouse strains has shown that some of the widely used behavioral methods yield inconsistent results across laboratories, in spite of standardization efforts. LÄS MER
