  1. 26. 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

    Sammanfattning : Enzyme immobilization on electrically conductive supports is necessary to improve their bioactivity and stability, for use and re-use in applications depending on bio-electrochemical response, such as in bioelectrodes, biosensors, or biofuel cells. However, the immobilization methods used are still facing many challenges in terms of health hazards and high environmental impact. LÄS MER

  4. 29. Protein stabilization. Some methods and mechanisms

    Författare :Maria Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorbitol; protein stability; preferential exclusion; polyol; poly-NIPAAm; polymer; poly ethyleneimine ; polyelectrolyte; oxidation; NMR spectroscopy; lysozyme; lactate dehydrogenase; fluorescence; dynamic light scattering; complex; additive; circular dichroism; stabilization; trypsin; thermo-reversible polymer.; Biotechnology; Bioteknik;

    Sammanfattning : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. LÄS MER

  5. 30. Lipid sponge phase nanostructures as carriers for enzymes

    Författare :Maria Valldeperas Badell; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sponge phase; lipid liquid crystals; DGMO; GMO-50; polysorbate 80; encapsulation of proteins; Aspartic protease; β-galactosidase; X-ray and neutron scattering; Raman spectroscopy; adsorption; cryo-TEM;

    Sammanfattning : Nonlamellar lipid liquid crystalline phases have many potential applications, such as for drug delivery, protein encapsulation or crystallization. Lipid liquid crystalline sponge phase (L3) has so far not been very much considered in these applications, in spite of apparent advantages in terms of its flexibility and capacity of forming large aqueous pores able to encapsulate large bioactive molecules.
