  1. 1. Discovery and investigation of glycoside hydrolase family 5 enzymes with potential use in biomass conversion

    Författare :Yang Wang; Henrik Aspeborg; Ines Ezcurra; Jerry Ståhlberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plant cell wall; biomass; hemicellulose; mannans; glycoside hydrolase; subfamily classification; Arabidopsis; mannanase; transglycosylase; enzymatic characterization.; Bioteknologi; Biotechnology;

    Sammanfattning : Glycoside hydrolases (GHs) cleave glycosidic bonds in glycoconjugates, oligosaccharides and polysaccharides such as cellulose and various hemicelluloses. Mannan is a major group of hemicelluloses. LÄS MER

  3. 2. Structure and functional studies of plant cell wall degrading enzymes : glycoside hydrolase family 3 β-glucosidases and lytic polysaccharide monooxygenases

    Författare :Mikael Gudmundsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Presently, plant biomass is considered as one of the major future renewable sources for the production of second-generation biofuels. While the first generation biofuels essentially are based on starch and sucrose rich feed stocks and which production may compete with food production, the second-generation biofuels may be based on lignocellulose as feedstock, which is less problematic from an ethical point of view.

  4. 3. In vitro accessibility of provitamin A carotenoids in vegetables and fruits - Effects of different process and preparation methods and estimation of vitamin A activity

    Författare :Ellen Hedrén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; provitamin A carotenoids; lactic acid fermentation; food matrix; cell wall degrading enzymes; vegetables; vitamin A activity; beta-carotene; red palm oil; fruits;

    Sammanfattning : Vitamin A deficiency is a major nutritional problem in many developing countries, caused chiefly by a diet with low retinol content. The bioefficacy of provitamin A carotenoids in plant foods is claimed to be insufficient to maintain a satisfactory vitamin A status. LÄS MER

  5. 4. Functional genomics of wood degradation and biosynthesis

    Författare :Alex S. Rajangam; Tuula Teeri; Johan Edqvist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; populus; xylogenesis; secondary cell wall; cellulose; hemicellulose; microarrays; transcript profiling; Other biology; Övrig biologi;

    Sammanfattning : Forest biotechnology is a fast emerging field of research. The application of biotechnological tools will enhance the quality of the forest products. The resultant value added and environmentally sustainable products are an absolute necessity in the future. LÄS MER

  7. 5. Mannan-hydrolysis by hemicellulases: enzyme-polysaccharide interaction of a modular beta-mannanase

    Författare :Per Hägglund; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; hemicellulase; beta-mannanase; carbohydrate-binding modules; Biokemi; metabolism;

    Sammanfattning : The enzymatic degradation of plant polysaccharides is a process of fundamental importance in nature which involves a wide range of enzymes. In this work, the structure and function of hemicellulose-degrading enzymes was investigated. The focus was on a beta-mannanase (TrMan5A) produced by the filamentous fungus Trichoderma reesei. LÄS MER
