  2. 16. Heterogeneous electron transfer studies with ligninolytic redox enzymes and living bacteria. Applications in biosensors and biofuel cells

    Author : Vasile Coman; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; mediated electron transfer; self-assembled monolayer; flow injection analysis; amperometric biosensor; E. coli; succinate:quinone reductase; biofuel cell; B. subtilis; whole-cell biosensor;

    Abstract : The catalytic properties and the inter-domain electron transfer of cellobiose dehydrogenase (CDH) from the ascomycete fungus Myriococcum thermophilum adsorbed on graphite and thiol (SAM) modified gold electrodes were investigated using cyclic voltammetry, flow injection amperometry and UV-Vis spectroelectrochemistry. The fabrication and characterisation of a noncompartmentalised, mediator and cofactor free glucose–oxygen biofuel cell well-operating in glucose-containing buffers and human blood serum was performed.

    Author : MNadeem Zafar; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Abstract : 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. READ MORE

  5. 18. Biosensors and Automation for Bioprocess Monitoring and Control

    Author : M A Kumar; Bioteknik; []
    Keywords : online monitoring; ELISA; immunosensor; flow injection; Biosensor; bioprocess; control; environmental;

    Abstract : Bioprocess monitoring and control is a complex task that needs rapid and reliable methods which are adaptable to continuous analysis. Process monitoring during fermentation is widely applicable in the field of pharmaceutical, food and beverages and wastewater treatment. READ MORE

  6. 19. Engineering of thermometric biosensors and characterisation of redox enzymes for improved performance of biosensors/biofuel cells

    Abstract : The present work is mainly focused on the development of enzyme-based bioanalytical devices, which can further be applied as analytical tools for industrial, medical and environmental applications. The first part of the work deals with the practical applications of thermometric biosensors for determination of various sugars (fructose and lactose) in a real samples. READ MORE

  7. 20. Improving the biocatalyst. Engineering of fungal oxidoreductases and thin-film electrodes for improvement of membraneless biofuel cells and carbohydrate biosensors

    Author : Roberto Ortiz; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellobiose dehydrogenase; pyranose dehydrogenase; biosensor; enzymatic biofuel cell; carbon nanotubes; gold nanoparticles; direct electron transfer; flow-injection analysis; diazonium salts; self-assembled monolayers;

    Abstract : 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. READ MORE
