This thesis describes the possibility of using hydrophobic peptide tags as tools for bioseparation and for the investigation of recombinant proteins. The hydrophobicity of a protein can easily be changed by minor modifications, such as fusions of tyrosine-containing peptides. The fusion tags may also increase both stability and expression of the fusion protein. Furthermore, a protein library with
Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. Carbon paste was used as the electrode material and served as the supporting matrix to incorporate the enzymes alcohol oxidase or pyranose oxidase. Hydrogen
Pharmaceuticals are today released into aquatic environments where they can interfere with organisms' biological processes.The general research objective was to analyze how aquatic freshwater organisms are affected by exposure to pharmaceuticals that are categorized by the EU as potential risk factors to the environment (i.e., 17α-Ethinylestradiol (EE2) and diclofenac). The main aim of this thesis
I detta konferensbidrag ifrågasätter jag åsikten att litteraturteori inte bör läras ut på gymnasienivå. Enligt den franske litteraturteoretikern Tzvetan Todorov bör läraren på denna nivå endast lära ut litterära verk, inte teori. Teorin borde endast användas som ett osynligt verktyg. Min hypotes är att litteraturteorin kan användas framgångsrikt på gymnasiet. Viss insikt i teorin kan bidra till atIn this paper I challenge the opinion that literary theory should not be taught at upper secondary level. According to French literary theorist Tzvetan Todorov, the teacher at this level should aim at teaching literary works, not theory. Theory should only be used as an invisible instrument. My hypothesis is that literary theory can be used successfully at upper secondary level. A certain insight
