16. Exploring and exploiting plant biomass degradation by Bacteroidetes
Abstract : Bacteroidetes bacteria have evolved to become excellent biomass degraders. They achieved this by applying carbohydrate-active enzymes (CAZymes) and organizing genes connected to the degradation of specific polysaccharides into discrete gene cassettes, so-called polysaccharide utilization loci (PULs).

17. 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

18. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites
Abstract : 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.

19. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results
Abstract : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. READ MORE

20. Aspects of extended impregnation kraft cooking for high-yield pulping of hardwood
Abstract : The long-term trend regarding wood is an increase in price. Because wood contributes to a large part of production costs, the efficient utilisation of wood is greatly desired to reduce production costs for kraft pulp producers. During the 1990s, the development of improved modified kraft cooking began, which led to higher yields. READ MORE
