2. 1. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

   Author : Christopher Schulz; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

   Abstract : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. READ MORE

4. 2. Functionality of Spray-Dried Whey Protein Powders - Surface Composition, Particle Morphology and Rehydration

   Author : Ida-Marie Andersson; Avdelningen för livsmedel och läkemedel; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality; Milk serum protein; Lactose; Whey protein powders; Spray drying; Particle morphology; Surface composition; Rehydration; Functionality;

   Abstract : Whey protein powder functionality is expected to be closely linked to both structure and properties of the proteins. It is essential that whey protein powders are easily dispersed and dissolved in order to fulfil the specified nutrient content and the functionality in the final product. READ MORE

5. 3. Beta-Glycosidases from Hyperthermophiles as Biocatalysts

   Author : Therese Hansson; Avdelningen för klinisk kemi och farmakologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biochemical technology; Biokemisk teknik; Proteins; enzymology; Proteiner; enzymologi; Biotechnology; high temperatures; water activity; activity; selectivity; hexanol; hexyl-b-glycoside; galacto-oligosaccharides; lactose; hyperthermostable b-glycosidase; hydrolysis; optimisation; transglycosylation;

   Abstract : The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. READ MORE

6. 4. Phase Transformations in Solid Pharmaceutical Materials Studied by AFM, ESCA, DSC and SAXS

   Author : Denny Mahlin; Göran Alderborn; Sven Engström; Duncan Q M Craig; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polymer; lipid; lactose; phase transformation; phase formation; crystallisation; AFM; X-ray diffraction; ESCA; DSC; solid dispersion; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

   Abstract : Mixing excipients is a common way to produce pharmaceutical materials with suitable properties for drug formulation. An understanding of the basic mechanisms involved in the formation and transformation of the structures of solid state mixtures is crucial if one is to be able to produce materials with the desired properties in a reliable way.

7. 5. Functional aspects of cellobiose dehydrogenase Applications for biosensor development

   Author : Leonard Stoica; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; Analytisk kemi; Analytical chemistry; bioelectrochemistry; direct electron transfer; lactose biosensor;

   Abstract : Electrochemcial investigations were conducted for elucidating and understanding the relation between the various electron transfer processes occurring in cellobiose dehydrogenase (CDH) bound to an electrode surface. Substrate inhibition caused by cellobiose was proven to act in competition with the electron transfer to a two-electron acceptor and under a partial inhibition mechanism for the internal electron transfer process.
