1. Process Development of Bioethanol Production from Wheat and Barley Residues Steam Pretreatment and SSF
Sammanfattning : Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. LÄS MER
2. Residues from biochemical production of transport biofuels in Northern Europe : combustion properties and applications
Sammanfattning : Residues from biochemical production of liquid transport biofuels will probably become available for energy use if more gasoline and diesel is substituted. For processes used in northern Europe they amount to 35-65 % of the feedstock energy and despite interest from energy companies, their fuel properties are largely unknown. LÄS MER
3. Integration of first and second generation bioethanol processes using edible filamentous fungus Neurospora intermedia
Sammanfattning : Establishing a commercial, lignocellulose-based, second-generation ethanol process has received several decades of attention by both researchers and industry. However, a fully economically viable process still remains a long-term goal. LÄS MER
4. Experimental studies of ash transformation processes in combustion of phosphorus-rich biomass fuels
Sammanfattning : The present thesis is a summary of eight papers dealing with experimental studies on bed agglomeration, slag formation, formation of deposits and fine particulate matter during combustion of phosphorus-rich biomass fuels. The experimental procedures were performed in a bubbling fluidized bed (5 kW), two fixed bed appliances (20 and 15 kW) and in a powder burner (150 kW). LÄS MER
5. Fungal production and solid state chemistry of eritadenine : an integrated approach to development of an active pharmaceutical ingredient
Sammanfattning : The present thesis demonstrates an integrated approach to the development of a potential active pharmaceutical ingredient, eritadenine, a cholesterol reducing compound originating from the shiitake mushroom (Lentinus edodes). The main areas covered in the thesis are a method for quantification of eritadenine, production of eritadenine by submerged cultivation of fungal mycelia and investigation of the influence of process parameters on mycelial growth and production, and finally solid state characterizations of eritadenine.
