1. 6. Heterologous expression, characterization and applications of carbohydrate active enzymes and binding modules

   Författare :Åsa Kallas; Tuula T. Teeri; Edward A. Bayer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Populus; xyloglucan endotransglycosylase; carbohydrate binding modules; endo- 1; 4 -b-xylanase; Escherichia coli; Pichia pastoris; N-glycosylation; fiber analysis; Bioengineering; Bioteknik; Wood fibre and forest products; Träfiber- och virkeslära;

   Sammanfattning : Wood and wood products are of great economical and environmental importance, both in Sweden and globally. Biotechnology can be used both for achieving raw material of improved quality and for industrial processes such as biobleaching. LÄS MER

3. 7. Mannan-hydrolysis by hemicellulases: enzyme-polysaccharide interaction of a modular beta-mannanase

   Författare :Per Hägglund; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; hemicellulase; beta-mannanase; carbohydrate-binding modules; Biokemi; metabolism;

   Sammanfattning : The enzymatic degradation of plant polysaccharides is a process of fundamental importance in nature which involves a wide range of enzymes. In this work, the structure and function of hemicellulose-degrading enzymes was investigated. The focus was on a beta-mannanase (TrMan5A) produced by the filamentous fungus Trichoderma reesei.

4. 8. 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

5. 9. Glycoside hydrolases from Rhodothermus marinus Modular organisation and structure-function relationships

   Författare :Maher Abou-Hachem; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium-binding; modular; endoglucanase; thermostable; CBM; xylanase; Biotechnology; Bioteknik;

   Sammanfattning : The thermophilic bacterium Rhodothermus marinus produces several thermostable glycoside hydrolases. The studies presented in this thesis were performed on two enzymes, belonging to glycoside hydrolase families 10 and 12, produced by this microorganism. The family 10 xylanase, Xyn10A, is modular in architecture consisting of five domains or modules. LÄS MER

7. 10. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis

   Författare :Alexandra Andersson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Physical chemistry; Fysikalisk kemi; enzymology; hydrogels; Plant biochemistry; Växtbiokemi; Proteins; a-galactosidase; b-mannanase; hemicellulase; corn fibre; barley husks; spruce; size-exclusion chromatography; arabinoxylan; microwave irradiation; steam pretreatment; membrane filtration; hemicellulose; galactoglucomannan;

   Sammanfattning : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. LÄS MER
