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

    Författare :Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
    Nyckelord :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. Structure and function studies of GH45 glycoside hydrolases

    Författare :Laura Okmane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The enzymatic hydrolysis of lignocellulosic material in nature is carried out by a plethora of cellulases. Glycoside hydrolase family 45 (GH45) enzymes are small cellulases most commonly found in fungi that catalyse the hydrolysis of β(1→4) linked glucans. LÄS MER

  4. 3. The relation between the supramolecular structure of cellulose and its hydrolysability

    Författare :Ausra Peciulyte; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose I; SHG; Cellulases; CARS; Imaging; Trichoderma reesei; MPEF; CP MAS 13C-NMR; Secretomics;

    Sammanfattning : The liberation of fermentable sugars from cellulosic biomass during enzymatic hydrolysis is often incomplete. One of the factors limiting the efficiency of enzymatic hydrolysis is the structural properties of cellulose. LÄS MER

  5. 4. Fungal cellulases: Study of hydrolytic properties of endoglucanases from Trichoderma reesei and Humicola insolens

    Författare :Johan Karlsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Humicola insolens; Trichoderma reesei; endoglucanases; cellulose hydrolysis; carboxymethyl cellulose; synergy; Biochemistry; Biokemi; Metabolism; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Cellulose is one of the most abundant biopolymers on earth. Several organisms degrade cellulose, one of the most studied is the fungus Trichoderma reesei which produces seven genetically different cellulases. LÄS MER

  7. 5. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose

    Författare :Veljo Sild; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. LÄS MER
