6. Adsorption of xylans on cellulosic fibres -Influence of xylan composition on adsorption characteristics and kraft pulp properties
Sammanfattning : Xylans are polysaccharides present in large amounts in cell walls of vascular plants. They possess an inherent affinity to cellulose and will thus adsorb irreversibly on cellulose surfaces. LÄS MER
7. On the Local Filtration Properties of LignoBoost lignin: Studies of the influence of xylan and ionic strength
Sammanfattning : Kraft pulping technology is currently the most commonly-used method for producing paper pulp from wood. A new and promising opportunity for Kraft pulp mills is to take a step towards becoming biorefineries by implementing technologies able to extract and convert the organic by-products, such as lignin, into a wide range of value-added products and chemicals.

8. Investigation of genes and proteins involved in xylan biosynthesis
Sammanfattning : Wood formation or xylogenesis is a fundamental process for so diverse issues as industry, shelter and a sustainable environment. Wood is comprised of secondary xylem, rigid large cells with thick cell walls that are lignified. LÄS MER
9. Conversion of xylan into value-added products
Sammanfattning : Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. LÄS MER
10. Improving cellulose fibre properties by controlled adsorption of xylans
Sammanfattning : Hemicelluloses are, together with cellulose and pectins, the polysaccharide constituents in the cell walls of higher plants. Xylans are the most common hemicelluloses, and are considered to be the second most abundant biopolymer in the plant kingdom. LÄS MER
