  1. 1. Transglycosylation by Glycoside Hydrolases - Production and modification of alkyl glycosides

    Författare :Pontus Lundemo; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glycoside hydrolases; Cyclodextrin glucanotransferases; β-glucosidases; Alkyl glycosides; Thermotoga neapolitana; Organic reaction media;

    Sammanfattning : To enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry. LÄS MER

  3. 2. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

    Författare :Zubaida Gulshan Kazi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

    Sammanfattning : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. LÄS MER

  4. 3. Degradation of wood polysaccharides by fungal glycoside hydrolases

    Författare :Torny Eriksson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Penicillium brasilianum; ethanol; cellulose; wood polysaccharides; Man5A hemicellulase; cellulase; endoglucanase; cellobiohydrolase; Cel7B; Cel7A; Trichoderma reesei; glycoside hydrolase; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The enzymatic degradation of wood polysaccharides such as cellulose and hemicellulose is an important process in nature. In addition, cellulases and hemicellulases can be used in industrial applications. Fuel ethanol can potentially be produced from wood by enzymatic hydrolysis of cellulose followed by yeast fermentation of the formed sugars. LÄS MER

  5. 4. Exploring thermostable glycoside hydrolases: Amylases and beta-glucosidases

    Författare :Pernilla Turner; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Proteiner; beta-glucosidase; thermostability; activity; cyclodextrinase; enzymology; crystallization; enzymologi; expression; glycoside hydrolase; Proteins; transglycosylation;

    Sammanfattning : Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. LÄS MER

  7. 5. 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
