  1. 1. 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

  3. 2. Enzyme Hydrolysis of Cellulose Derivatives. Active Site Studies and Polymer Characterisation

    Författare :Herje Schagerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Humicola insolens; Trichoderma reesei; Bacillus agaradhaerens; Mass spectrometry; Substituent distribution; Characterisation; Endoglucanases; Cellulose derivatives;

    Sammanfattning : Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. LÄS MER

  4. 3. Lipase selectivity in functional polyester synthesis

    Författare :Cecilia Hedfors; Karl Hult; Romas Kazlauskas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : Enzyme selectivity means that the enzyme´s preferences towards competing substrates will be different. In this thesis, the enzyme selectivity has been studied for utilization in synthesis of functionalized macromonomers. LÄS MER

  5. 4. Enzyme substrate solvent interactions : a case study on serine hydrolases

    Författare :Linda Fransson; Karl Hult; Jürgen Pleiss; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipase; esterase; specificity; Bioengineering; Bioteknik;

    Sammanfattning : Reaction rates and selectivities were measured for transacylation of fatty acid esters in solvents catalysed by Candida antarctica lipase B and by cutinase from Humicola insolens. With these enzymes classical water-based enzymology can be expanded to many different solvents allowing large variations in interaction energies between the enzymes, the substrates and the surrounding.

  7. 5. 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
