  1. 11. Bacteria-responsive materials for drug delivery

    Författare :Marina Craig; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; triggered release; multilayer; controlled release; Layer-by-layer; nanofilm; infection; enzymatic degradation;

    Sammanfattning : The number of diabetics, obese individuals and other patients carrying other lifestyle diseasesis increasing worldwide. At the same time the population is ageing. These patients all sufferfrom poor blood circulation, which often gives rise to non-healing, or chronic, wounds. Thus,the number of chronic wounds is also increasing at a fast pace. LÄS MER

  3. 12. Analysis of Degradation Products from Wood and Methods for Detoxification of Lignocellulose Hydrolysates

    Författare :Per Persson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; galactoglucomannan; mass spectrometry; liquid chromatography; sugar degradation; detoxification; fermentation inhibitors; lignocellulose hydrolysates; Ethanol production; softwood; Analytical chemistry; Analytisk kemi; countercurrent supercritical fluid extraction;

    Sammanfattning : In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. LÄS MER

  4. 13. Formyl-coenzyme : a transferase, structure and enzymatic mechanism

    Författare :Stefano Ricagno; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :X-ray crystallography; oxalate degradation; Oxalobacter; CoA transferase; interlocked dimer; anhydride.;

    Sammanfattning : Background: Formyl-CoA transferase (Frc) is the first enzyme in a two enzyme pathway responsible for oxalate degradation in Oxalobacter formigenes. This bacterium is a constitutive part of human intestinal flora. Its role as an oxalate scavenger is very important, reports have shown a strong connection between the disappearance of 0. LÄS MER

  5. 14. Degradation of wood polysaccharides by fungal glycoside hydrolases

    Författare :Torny Eriksson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Penicillium brasilianum; ethanol; cellulose; wood polysaccharides; Man5A hemicellulase; cellulase; endoglucanase; cellobiohydrolase; Cel7B; Cel7A; Trichoderma reesei; glycoside hydrolase; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The enzymatic degradation of wood polysaccharides such as cellulose and hemicellulose is an important process in nature. In addition, cellulases and hemicellulases can be used in industrial applications. Fuel ethanol can potentially be produced from wood by enzymatic hydrolysis of cellulose followed by yeast fermentation of the formed sugars. LÄS MER

  7. 15. Hydrolytic and Oxidative Mechanisms Involved in Cellulose Degradation

    Författare :Anu Nutt; Jerry Ståhlberg; Henrik Stålbrand; Uppsala universitet; []
    Nyckelord :Biochemistry; cellobiohydrolase; cellulase; cellulose; cellobiose dehydrogenase; endoglucanase; kinetics; synergism; competitive binding; Biokemi;

    Sammanfattning : The enzymatic degradation of cellulose is an important process in nature. This thesis has focused on the degradation of cellulose by enzymes from two cellulose-degrading fungi, Hypocrea jecorina and Phanerochaete chrysosporium, including both the action of the individual enzymes and their synergistic interplay.
