    Författare :Anna Ottenhall; Monica Ek; Josefin Illergård; Orlando Rojas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

  3. 17. Characterization of extracellular and surface bound adherence proteins of Staphylococcus aureus

    Författare :Torgny Schennings; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Staphylococcus aureus;

    Sammanfattning : Staphylococcus aureus (S.aureus) is a pathogen causing infections. In recent years S.aureus formed resistance to most of known antibiotics on the market. LÄS MER

  4. 18. Baeyer-Villiger Monooxygenases from a Dietzia sp. - Enzyme Discovery, Characterization and Engineering

    Författare :Serena Bisagni; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dietzia; Baeyer-Villiger monooxygenases; biocatalysis; enzyme;

    Sammanfattning : With the emergence of Green Chemistry, biocatalysis is becoming an important approach in many laboratory and industrial processes. Enzymes catalyse chemical reactions with high regio- and stereoselectivity at mild conditions and, most importantly, are able to form products that are not possible to obtain by conventional synthetic chemistry.

  5. 19. Glycoside hydrolases from Rhodothermus marinus Modular organisation and structure-function relationships

    Författare :Maher Abou-Hachem; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium-binding; modular; endoglucanase; thermostable; CBM; xylanase; Biotechnology; Bioteknik;

    Sammanfattning : The thermophilic bacterium Rhodothermus marinus produces several thermostable glycoside hydrolases. The studies presented in this thesis were performed on two enzymes, belonging to glycoside hydrolase families 10 and 12, produced by this microorganism. The family 10 xylanase, Xyn10A, is modular in architecture consisting of five domains or modules. LÄS MER
