1. Production and investigation of highly thermophilic multi-domain carbohydrate-active enzymes
Sammanfattning : With the looming threat of climate change caused largely by an excess of carbon dioxide in the atmosphere, recent scientific efforts have focused on the substitution of fossil fuels and other polluting compounds with more environmentally conscious choices. To this end, the investigation of biomass as both a renewable source of energy and as a chemical basis to produce high-value products is being extensively investigated. LÄS MER
2. Heterocystous cyanobacteria, Dps proteins and H2 production
Sammanfattning : To mitigate climate change, CO2-emitting technologies have to be exchanged by renewable alternatives such as H2. H2 can be produced by cyanobacteria, but major efforts to enhance H2 production yields by genetic modifications or optimised cultivation conditions resulted in energetic photo-to-H2 conversion efficiencies of 4.

3. Toxin production in clostridium difficile
Sammanfattning : Clostridium difficile is a is a Gram potential human pathogen. It causing symptoms ranging from mild C. difficile associated diarrhea (CDAD) to severe inflammation of the colon including pseudomembranous colitis and fulminant colitis. Over 300 000 and about 10 000 CDAD episodes are diagnosed annually in the USA and Sweden, respectively. LÄS MER
4. The effect of protein intake and physical exercise on energy turnover and substrate utilisation at energy balance in man
Sammanfattning : The principal goal of the thesis has been to evaluate the effect of protein intake and physical exercise on energy turnover and substrate utilisation. Body composition assessment is of importance as an indicator of the energy balance. Therefore, in the first study the aim was to develop new models to estimate body composition more accurately.

5. Aspects of extended impregnation kraft cooking for high-yield pulping of hardwood
Sammanfattning : 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. LÄS MER
