16. Functional and Renewable Galactoglucomannan-based Hydrogels
Sammanfattning : Polysaccharides represent an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Here they are, due to their natural diversity found in many special applications, e.g. in the biomedical sector. LÄS MER
17. Hemicelluloses and other Polysaccharides for Wood Adhesive Applications
Sammanfattning : The growing environmental awareness has led to an increased interest in bio-based polymers as replacement for fossil-based materials. The purpose of the work described in this thesis was to investigate the possibility of using hemicelluloses and other polysaccharides as replacement for fossil-based polymers in wood adhesives.

18. Quinoa Stalks Glucuronoarabinoxylan : Biorefinery,xylooligosaccharides production and potential applications
Sammanfattning : Quinoa stalks were used as a source of hemicellulose for XOs production and further as prebiotic source for probiotic bacteria. Three methods for extraction of hemicellulose were used, of which alkaline extraction (NaOH [0.5 M]) was the optimum method. LÄS MER
19. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites
Sammanfattning : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

20. Xylan biosynthesis and modification : characterisation of a glycosyltransferase and a glycoside hydrolase in hybrid aspen
Sammanfattning : Wood is an important renewable material used by humans for a variety of downstream applications. The basic subcellular structure in wood is the cell wall, mainly consisting of the cross-linked polymers cellulose, hemicellulose, and lignin. LÄS MER
