  1. 1. Cellulose hydrolysis by Trichoderma reesei cellulases: Studies on adsorption, sugar production and synergism of cellobiohydrolase I, II and endoglucanase II

    University dissertation from Department of Biochemistry, Lund University

    Author : Jozsef Medve; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FPLC; cellulose hydrolysis; Trichoderma reesei; cellulase; cellobiohydrolase; endoglucanase; adsorption isotherm; synergism; enzyme purification; isoenzymes; quantitative analysis; Biochemistry; Metabolism; Biokemi;

    Abstract : Three major cellulases, cellobiohydrolase I and II (CBH I and II) and endoglucanase II (EG II) of Trichoderma reesei have been purified by ion-exchange chromatography in an FPLC system. Microcrystalline cellulose (Avicel) was hydrolysed by the single enzymes and by equimolar mixtures of CBH I-CBH II and CBH I-EG II. READ MORE

  2. 2. The kinetics of cellulose enzymatic hydrolysis Implications of the synergism between enzymes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Priit Väljamäe; Jan-Christer Janson; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. READ MORE

  3. 3. Enantioselective Binding of Designed Propranolol Analogues to the Cellobiohydrolase Cel7A

    University dissertation from Organic Chemistry, Lund University

    Author : Alexandra Fagerström; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strukturkemi; Structure chemistry; enzymologi; Proteiner; enzymology; Proteins; Naturvetenskap; Natural science; capillary electrophoresis; chiral recognition; enantiomeric selectivity; cellobiohydrolase Cel7A; propranolol; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes the affinity and enantiomeric selectivity of the cellobiohydrolase Cel7A (isolated from Hypocrea jercorina). The chiral recognition of the enzyme has been studied with respect to amino alcohols and new ligands have been designed, based on the structure of the common ?-blocker propranolol. READ MORE

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

    University dissertation from Torny Eriksson Dept of Biochemistry, Lund University

    Author : Torny Eriksson; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Penicillium brasilianum; ethanol; cellulose; wood polysaccharides; Man5A hemicellulase; cellulase; endoglucanase; cellobiohydrolase; Cel7B; Cel7A; Trichoderma reesei; glycoside hydrolase; Plant biochemistry; Växtbiokemi;

    Abstract : 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. READ MORE

  5. 5. Aspects of Optimisation of Separation of Drugs by Chemometrics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Valérie Harang; Douglas Westerlund; Sven P. Jacobsson; Bo Karlberg; [2003]
