    Sammanfattning : Better utilization of renewable sources of energy and recovery of resources from waste streams are important challenges for researchers. Bioelectrochemical systems (BESs) are new technologies which e.g. could be used to produce green energy from waste sources or store renewable electricity as chemical fuels. LÄS MER

  3. 2. Influence of electrode material and stochastic factors on the performance and microbial community assembly in microbial electrochemical systems

    Författare :Marie Abadikhah; Chalmers tekniska högskola; []

    Sammanfattning : Microbial electrolysis cells (MECs) are systems with microbial communities in the form of biofilms on electrode surfaces. The electrogenic bacteria in the anode biofilm act as catalysts for the oxidization of organic compounds, leading to release of electrons, generation of electrical current, and production of hydrogen and methane at the cathode.

    Sammanfattning : 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

  7. 5. Design and characterization of direct electron transfer based biofuel cells including tests in cell cultures

    Författare :Peter Lamberg; Malmö högskola; []
    Nyckelord :biofuel cell; enzymatic fuel cell; direct electron transfer; cellobiose dehydrogenase; biocompatibility; enzyme kinetics; cell culture;

    Sammanfattning : Enzymatic fuel cells (EFCs) are bioelectronic devices based on redox enzymes, which convert chemical energy into electrical energy via biochemical reactions. A major difficulty to overcome is to successfully connect (using e.g., immobilization) the enzymes to the electrode surface. LÄS MER
