11. Mercerization and Enzymatic Pretreatment of Cellulose in Dissolving Pulps
Abstract : This thesis deals with the preparation of chemically and/or enzymatically modified cellulose. This modification can be either irreversible or reversible. Irreversible modification is used to prepare cellulose derivatives as end products, whereas reversible modification is used to enhance solubility in the preparation of regenerated cellulose.

12. Nutritional and physicochemical characterisation of dietary fibre in wheat fractions
Abstract : Dietary fibre is fermented in the colon to short-chain fatty acids (SCFAs), of which especially butyric and propionic acid may have health-promoting effects. One source of dietary fibre may be by-products from wheat, which are currently used as animal feed. READ MORE

13. RECOMBINANT PEROXIDASES AND XYLANASES: I. Cloning and production of a peroxidase from horseradish II. Characterisation of functional domains of thermostable xylanases from Rhodothermus marinus
Abstract : Part I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. READ MORE

14. Fibrous feeds for functional fowls
Abstract : Fibres are not digested by fowls, but their impact on digestive physiology, nutrient metabolism and intestinal microflora can be substantial. Analytical shortcomings have historically contributed to different notions on the significance of fibres, but modern techniques now enable us to better discriminate between various fractions of fibre and relate them with the performance of poultry.

15. Kraft Pulp Fibre Surfaces. Chemical Composition and Effect on Pulp Bleachability
Abstract : The work presented in this thesis concerns studies of kraft fibre surfaces in respect of chemical composition and effect on pulp bleachability. Kraft fibre surfaces were studied by mechanical peeling using a disintegrator operated at 20.000-200.000 revolutions and a pulp consistency of 3% or 4. READ MORE
