  1. 6. Enzymatic Synthesis of Alkyl Glycosides. New Applications for Glycoside Hydrolases

    Författare :David Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGTase; cyclodextrin glycosyltransferase; alkyl glycoside; enzyme stabliity; enzymatic synthesis; enzyme immobilisation; surfactant; glycosylation;

    Sammanfattning : The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. LÄS MER

  3. 7. Lipase-catalyzed production of structured triacylglycerols

    Författare :Ariana Causevic; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structured lipids; Lipase; Acyl migration; Immobilization; Lipid analysis; Transesterification; Water activity;

    Sammanfattning : Vegetable oils and fats are major energy sources but also play an essential part in the physical and chemical properties of food products. The current change in the climate is affecting harvest yields, leading to a shortage and increased prices of raw materials that are difficult to replace. LÄS MER

  4. 8. Nanoporous Aluminum Oxide – A Promising Support for Modular Enzyme Reactors

    Författare :Marcus Kjellander; Gunnar Johansson; Gunnar Henriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoporous aluminum oxide; immobilized enzymes; bioreactor; Biokemi; Biochemistry;

    Sammanfattning : Nanoporous alumina is a rather newly characterized material that so far has found limited use in the construction of bioreactors. The material has many advantages compared to conventional immobilization matrices. I have investigated its use in flow-through bioreactors. LÄS MER

  5. 9. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis

    Författare :Ratana Lawung; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Metabolism; Biochemistry; enzyme calorimeter; site-directed mutagenesis; ampicillin resistance plasmid; Haemophilus ducreyi; TEM-1 b-lactamase; metabolism; Proteins; enzymology; Proteiner; enzymologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. LÄS MER

  7. 10. Investigation of Carbohydrate Hydrolysing Enzymes in Applications for Characterisation and Synthesis of Carbohydrates

    Författare :Carina Nilsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; enzyme hydrolysis; characterisation of carbohydrates; Analytical chemistry; mass spectrometry;

    Sammanfattning : Cellulose and starch are non-toxic, biodegradable and modifiable polymers. These properties have made them increasingly important in industrial products e. g. in pharmaceutical applications and in technical dispersions. LÄS MER
