21. Waste Textiles Bioprocessing to Ethanol and Biogas
Sammanfattning : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. LÄS MER
22. Determination of Fat-Soluble Vitamins in Foods Based on Supercritical Fluid Extraction
Sammanfattning : Sample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. LÄS MER
23. Isolation, characterization and enzymatic hydrolysis of water-soluble wood polysaccharides
Sammanfattning : The need for new renewable products has enhanced the interest in cellulose and hemicellulose as raw material. The wood plant cell wall is a complex mixture of cellulose, hemicellulose, lignin and minor amounts of pectin, proteins and extractives. Several interactions between the compounds make them difficult to separate without modification. LÄS MER
24. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis
Sammanfattning : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. LÄS MER
25. Enzyme Hydrolysis of Cellulose Derivatives. Active Site Studies and Polymer Characterisation
Sammanfattning : Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. LÄS MER
