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

    Författare :Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : 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. LÄS MER

  3. 2. Bioethanol Production: Pretreatment and Enzymatic Hydrolysis of Softwood

    Författare :Charlotte Tengborg; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recirculation of process streams; detoxification; inhibition; hydrolysis conditions; enzymatic hydrolysis; Ethanol production; steam pretreatment; softwood; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Sammanfattning : The enzymatic hydrolysis process can be used to produce bioethanol from softwood, which are the dominating raw material in the Northern hemisphere. This thesis deals with the development of the process focusing on the pretreatment and the enzymatic hydrolysis stages. LÄS MER

  4. 3. Engineering carbonic anhydrase for highly selective ester hydrolysis

    Författare :Gunnar Höst; Bengt-Harald Jonsson; Lars-Göran Mårtensson; Per Berglund; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; carbonic anhydrase; specificity; hydrolysis; rational design; protein engineering; plasmodium falciparum; Bioengineering; Bioteknik;

    Sammanfattning : I denna avhandling presenteras arbete utfört med enzymet humant karboanhydras II (HCAII). Enzymer är en typ av proteiner som accelererar (katalyserar) kemiska reaktioner, vilket är nödvändigt för allt levande. Den naturliga funktionen för HCAII är att katalysera omvandlingen av gasen koldioxid till vätekarbonat, som är löslig i vätska. LÄS MER

  5. 4. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

    Författare :Zubaida Gulshan Kazi; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  7. 5. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    Författare :Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Sammanfattning : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. LÄS MER
