Recombinant expression of transglutaminase from Atlantic cod in E. coli
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Transglutaminases (TGs) are a family of enzymes that catalyzes cross linking of proteins by forming covalent bonds between lysine residues and glutamine residues in different polypeptides. Cross-linking reactions are ... -
Limitations of the Revised DREAM Model
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)DREAM (Dose-related Risk and Exposure Assessment Model) is a risk assessment tool for modeling offshore waste discharge to the marine environment. The drilling waste model was developed through the joint industrial project ... -
Validering og anvendelse av ELISA-metode for å måle myeloperoksidase i plasma
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Myeloperoksidase (MPO) er et enzym som spiller en viktig rolle for immunforsvarets bekjempelse av bakterier. Enzymet frigjøres fra hvite blodceller under en inflammasjonsreaksjon og katalyserer dannelsen av det bakteriedrepende ... -
The influence of nitrogen on compounds and quality of Arabidopsis thaliana and tomato
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Part A: The influence of nitrogen on compounds and quality of Arabidopsis thaliana Flavonoids are secondary metabolites in plants that are thought to have beneficial effects on human health, as well as importance for ... -
Possible inhibitory effect of selected detergents used in food industry on wastewater treatment and especially on Grødaland wwtp.
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Grødaland waste water treatment plant (wwtp) is treating industrial waste water coming from food industry. As food industry consumes large amounts of detergents for food processing equipment cleaning, the wwtp receives ... -
Reduction of scaling in biological treatment of industrial waste water at SART
