21. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies
Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER
22. Solid-liquid Phase Equilibria and Crystallization of Disubstituted Benzene Derivatives
Sammanfattning : The Ph.D. project compiled in this thesis has focused on the role of the solvent in solid-liquid phase equilibria and in nucleation kinetics. Six organic substances have been selected as model compounds, viz. LÄS MER
23. Biobased Adipic Acid - Challenges in Establishing a Cell Factory
Sammanfattning : Growing concern regarding climate change calls for sustainable solutions to significantly reduce our dependency on non-renewable fossil-based raw materials. One potential solution is the development of biorefineries where biobased, renewable raw materials are converted into valuable products via enzymatic, chemical or microbial conversion. LÄS MER
24. Fermentation of wheat starch hydrolysate by Lactococcus lactis: Factors affecting product formation
Sammanfattning : Lactic acid exists as two optical isomers, D- and L-lactic acid. For the production of biodegradable poly-lactic acid an optically pure product is desirable, but a racemate of known and constant ratio can also be used. Lactic acid can be produced either synthetically or fermentatively. LÄS MER
25. Fatty acid amide hydrolase - A target for anti-inflammatory therapies?
Sammanfattning : Anti-inflammatory drugs are a widely used class of therapeutic agents, but the use of non-steroidal anti-inflammatory drugs (NSAID) is hampered by their gastrointestinal side-effects. Recent reports that cyclooxygenase-2 inhibitors may cause cardiovascular events underline the importance of identifying new therapeutic strategies for the treatment of inflammation. LÄS MER
