  1. 1. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology

    Författare :Oksana Zaushitsyna; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cells; Crosslinkers; PVA PEI; Immobilization; Biocatalysts; Biobased chemicals; Biotransformation; stress tolerance;

    Sammanfattning : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. LÄS MER

  3. 2. Biocatalyst Engineering: Metabolic Engineering, Kinetic modeling and metagenomics applied to industrial biotechnology

    Författare :Nadia Skorupa Parachin; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial biocatalysts; metagenomics; biocatalyst; Saccharomyces cerevisiae;

    Sammanfattning : Industrial biotechnology has been defined as the use and application of biotechnology for the sustainable processing and production of chemicals, materials and fuels. It makes use of biocatalysts such as microbial communities, whole-cell microorganisms or purified enzymes. LÄS MER

  4. 3. Beta-Glycosidases from Hyperthermophiles as Biocatalysts

    Författare :Therese Hansson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biochemical technology; Biokemisk teknik; Proteins; enzymology; Proteiner; enzymologi; Biotechnology; high temperatures; water activity; activity; selectivity; hexanol; hexyl-b-glycoside; galacto-oligosaccharides; lactose; hyperthermostable b-glycosidase; hydrolysis; optimisation; transglycosylation;

    Sammanfattning : The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. LÄS MER

  5. 4. Thermostable glycosidases and glycosynthases as biocatalysts in green chemistry applications

    Författare :Tania Pozzo; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green chemistry; 3D sturcture; Glycosyl hydrolases; Glycosynthases; Alkyl glucosides; Oligosaccharides; Flavonoids;

    Sammanfattning : The constant need to develop environmental friendly processes using renewable raw materials and to reduce harmful waste production motivates the present investigation focusing on biocatalyst development for enzymatic synthesis, a biotechnological approach in the field of green chemistry. At first, structural functional experiments were made for a β-glucosidase from T. LÄS MER

  7. 5. Hydrolases as Catalysts for Green Chemistry and Industrial Applications - Esterase, Lipase and Phytase

    Författare :Yasser Gaber; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPLC-EAT; sustainable environment; mutation; metallo-enzyme; phytate; b-propeller; biodegraqdable; metrics; green chemistry; Novozym 435; CalB; solvent-free; kinetic resolution; Biocatalysis; rational design; PLE; esterase; clopidogrel; enantioselectivity;

    Sammanfattning : The use of enzymes in industrial applications has been recognised for providing clean processes with minimal impact on the environment. This thesis presents studies on engineering of enzymes and enzyme-based processes in the light of green chemistry and environmental sustainability, and focuses on three hydrolases: esterase, lipase and phytase.
