  1. 1. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

    Författare :Christopher Schulz; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

    Sammanfattning : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. LÄS MER

  3. 3. 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

  4. 4. Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species

    Författare :Thitiwut Vongkampang; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor kronotskyensis; volumetric hydrogen productivity; non-diauxic; acrylic fibres; cell immobilization; chitosan; biofilm; c-di-GMP; cellobiose; xylose; consolidated bioprocessing; heat-treated wheat straw;

    Sammanfattning : Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. LÄS MER

  5. 5. Structural studies on the extracellular flavocytochrome cellobiose dehydrogenase from Phanerochaete chrysosporium

    Författare :Martin Hällberg; Andrea Mattevi; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; cellobiose dehydrogenase; flavocytochrome; hydride transfer; radical mechanism; X-ray crystallography; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Biology; with specialization in structural biology; biologi; med inriktning mot strukturbiologi;

    Sammanfattning : Microorganisms that degrade lignocellulose play an important role in maintaining the global carbon cycle. Under cellulolytic conditions, the fungus Phanerochaete chrysosporium produces an extracellular flavocytochrome, cellobiose dehydrogenase (CDH), with a proposed role in lignocellulose degradation.
