6. Ethanol from Lignocellulose - Fermentation Inhibitors, Detoxification and Genetic Engineering of Saccharomyces cerevisiae for Increased Resistance
Abstract : Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars, and then fermenting the hydrolysate with the yeast Saccharomyces cerevisiae. Hydrolysis using dilute sulphuric acid has advantages over other methods, however, compounds which inhibit fermentation are generated during this kind of hydrolysis. READ MORE

7. Asymmetrical Flow Field-Flow Fractionation in the Separation, Characterization and Application of Wine Particle Matter
Abstract : Wine particle matter is mainly constituted by wine colloids and wine macromolecules. These wine colloidal and macromolecular compounds are barely studied, possibly due to the difficulty in facing the challenges that their study merits. READ MORE

10. Process development and environmental assessment within softwood based biorefineries
Abstract : We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).
