  1. 1. Catalytically active and corrosion resistant cobalt-based thin films

    Author : Clara Linder; Emma Björk; Per Eklund; Sara Munktell; Anna Martinelli; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Oxygen reduction reaction; Corrosion; Thin film.;

    Abstract : Oxygen reduction reaction (ORR) has considerable potential for the pro-duction of electricity, issues with water splitting and many other applications in the energy sector. But in order to increase the efficiency of the reaction an electrocatalyst needs to be introduced. READ MORE

  2. 2. RECOMBINANT PEROXIDASES AND XYLANASES: I. Cloning and production of a peroxidase from horseradish II. Characterisation of functional domains of thermostable xylanases from Rhodothermus marinus

    Author : Eva Bartonek Roxå; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous cellulose; xylan; CBD; carbohydrate binding domains; insect cells; Baculovirus; catalytically active; recombinant horseradish peroxidase; HRP-n; PASC; beta-glucan; Biotechnology; Bioteknik;

    Abstract : Part I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. READ MORE

  3. 3. Conformational Studies of Biologically Active Peptides

    Author : Björn Walse; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PapD chaperone; P pili; desmopressin; DDAVP; protein-peptide interactions; glycopeptides; peptide design; transferred NOE; molecular dynamics simulations; circular dichroism; peptide conformation; NMR spectroscopy; immunogenic glycopeptides; Physical chemistry; Fysikalisk kemi;

    Abstract : In this work conformational studies have been performed on peptides from four different systems in an attempt to gain knowledge about their biological function. Circular dichroism (CD) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy in combination with distance geometry and restrained molecular dynamics simulations were the methods used.

  4. 4. Production and investigation of highly thermophilic multi-domain carbohydrate-active enzymes

    Author : Daniel Krska; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein structure; xylanase; carbohydrate esterase; multidomain enzymes; carbohydrate-active enzymes; thermostable enzymes; plant biomass degradation; Caldicellulosiruptor;

    Abstract : With the looming threat of climate change caused largely by an excess of carbon dioxide in the atmosphere, recent scientific efforts have focused on the substitution of fossil fuels and other polluting compounds with more environmentally conscious choices. To this end, the investigation of biomass as both a renewable source of energy and as a chemical basis to produce high-value products is being extensively investigated. READ MORE

  5. 5. Chiral recognition on cellulases : The active sites of the enzymes are involved

    Author : Hongbin Henriksson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Two cellobiohydrolases (CBH I and CBH II) and endoglucanase I (EG I) fromTrichoderma reesei, and CBH 58 from Phanerochaete chrysosporium were immobilized onsilica as chiral stationary phases (CSPs) in HPLC for enantioseparation of a group ofpharmaceutical compounds. CBH I and CBH 58 wore excellent chiral selectors for β-adrenergic blocking agents, whereas CBH II displayed good enantioselectivity for someother compounds The CBHs share the common feature that their active sites are located intunnels.
