6. galactmannan degradation by fungi and gut bacteria : structural enzymology and fine -tuned substrate specifcity
Abstract : AbstractThe degradation of plant based β-mannan polysaccharides represents one of the many challenges efficiently tackled by microorganisms living in different habitats. In this thesis, glycoside hydrolases (GHs) involved in mannan degradation from two different organisms, Aspergillus nidulans (paper I and II) and Bacteroides ovatus (paper III and IV) were studied.

7. Functional studies of a membrane-anchored cellulase from poplar
Abstract : Cellulose in particular and wood in general are valuable biomaterials for humanity, and cellulose is now also in the spotlight as a starting material for the production of biofuel. Understanding the processes of wood formation and cellulose biosynthesis could therefore be rewarding, and genomics and proteomics approaches have been initiated to learn more about wood biology.

8. Beta-Glycosidases from Hyperthermophiles as Biocatalysts
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

9. Exploring thermostable glycoside hydrolases: Amylases and beta-glucosidases
Abstract : Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. READ MORE

10. Transglycosylation by Glycoside Hydrolases - Production and modification of alkyl glycosides
Abstract : To enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry. READ MORE
