    Sammanfattning : Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER

    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.

    Sammanfattning : This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying the bioelement or by modifying the electrode. LÄS MER
