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

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

    Abstract : 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. READ MORE

  4. 2. Enzymatic Synthesis of Functional Polyesters

    Author : Mohamad Takwa; Karl Hult; Pål Nyren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : Enzymes are successfully employed in the synthesis of different types of polymers. Candida antarctica lipase B is a highly efficient catalyst for the synthesis of polyesters by ring opening polymerization. ω-Pentadecalactone is an interesting lactone due to the unique proprieties of its polymer (poly-pentadecalactone).

  5. 3. Surfactants based on natural products - enzymatic synthesis and functional characterization

    Author : Fredrik Viklund; KTH; []
    Keywords : Enzymatic synthesis; Surfactants; Antioxidants; Ascorbyl oleate; Polyethylene glycol PEG esters; Hemolysis; Transepithelial electrical resistance; Ionic liquids; Candida antarctica lipase B;

    Abstract : Surfactants are molecules that contain a water-soluble and afat-soluble part. They have important functions in productssuch as detergents, cosmetics, pharmaceuticals and foods aswell as in many industrial processes. Surfactants are used onvery large scale, which makes it important to decrease theirimpact on the environment. READ MORE

  6. 4. Transglycosylation catalyzed by β-mannanases : Molecular aspects relevant for enzymatic synthesis

    Author : Johan Morrill; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; β-mannanase; glycoside hydrolase; enzymology; kinetics; MALDI-TOF MS; HPLC; transglycosylation; alcoholysis; enzyme engineering; protein structure; enzymatic synthesis;

    Abstract : β-Mannanases are a major type of enzyme involved in the hydrolysis and modification of β-mannans, a hemicellulose present in high amounts in e.g. softwoods such as spruce. The β-mannanases studied in this thesis belong to glycoside hydrolase (GH) families GH5 and GH26. READ MORE

  7. 5. Enzymatic Synthesis of Mixed Acid Phospholipids

    Author : Dietlind Adlercreutz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lysophosphatidylcholine; phosphatidylcholine; acyl migration; equilibrium; organic solvent; lipase; phospholipase; Biotechnology; Bioteknik;

    Abstract : Mixed acid phospholipids are valuable compounds, which are used mainly in membrane- and lipoprotein research and in liposome technology. The chemical synthesis of these special lipids is rather difficult and involves both toxic chemicals and harsh reaction conditions, which makes the products less attractive for medical and biological applications.
