A detailed study of substrate positioning in family 18 chitinases
(PhD Thesis;2011:41, Doctoral thesis, 2011)Chitin is a linear polymer consisting of β-1,4-linked N-acetyl-glucosamine (GlcNAc; A) units tightly packed in a crystalline structure. It is produced by living organisms in large quantities per year and is a structural ... -
Applied and fundamental perspectives on brown-rot decay mechanisms
(PhD Thesis;2019:14, Doctoral thesis, 2019)Woody biomass is an important material for the growing bioeconomy, and has gained significant attention as a feedstock for second-generation biorefineries. Wood has traditionally been used as a building material for ... -
Class II bacteriocins : target recognition, resistance and immunity
(PhD Thesis;2011:11, Doctoral thesis, 2011)Bacteriocins are bacterial antimicrobial peptides which are active against strains often closely related to the producer. Bacteriocins produced by food grade lactic acid bacteria are considered promising for applications ... -
Dissecting molecular properties of honey bee vitellogenin : a protein acting at the intersection between social behavior and aging
(PhD Thesis;2011:59, Doctoral thesis, 2011)Vitellogenin is a central honey bee (Apis mellifera) life-history regulator. This thesis represents an initiative to study this protein, which affects aging and task-division of the bees, at the molecular level. I have ... -
Exploration of multi-response multivariate methods
(PhD Thesis;2019:76, Doctoral thesis, 2019)A linear regression model defines a linear relationship between two or more random variables. The random variables that depend on other random variables are often called response variables and the independent random variables ... -
Exploring acetylated galactoglucomannan as a source of prebiotics
(Doctoral thesis, 2018)The wood and paper industry in Norway and worldwide suffers from low demand and low prices. Developing consolidated biorefinery solutions to generate higher value products from woody biomass could be a viable alternative ... -
Full circle : genetics, biosynthesis, mode of action and resistance mechanisms of the bacteriocin garvicin ML
(PhD Thesis;2013:68, Doctoral thesis, 2013)Bacteriocins are ribosomally synthesized antimicrobial peptides, produced by many lactic acid bacteria, which show high promise as antimicrobial agents for use in both food industry and for medical applications. In this ... -
Knowledge-based methods handling complex dependency structures : applications to gene expression data
(PhD Thesis;2011:46, Doctoral thesis, 2011)Microarray gene expression data are usually associated with a large number of correlated variables measured on few samples. This type of data typically contain high levels of noise, and the biological signals may be difficult ... -
Natural transformation in Streptococcus thermophilus : Regulation autolysis and ComS*-controlled gene expression.
(PhD Thesis;2011:67, Doctoral thesis, 2011)Natural genetic transformation has been extensively studied in Streptococcus pneumoniae for generations, and much has been learned about this important phenomenon since its discovery by Frederick Griffith in 1928. In ... -
Regulation of energy metabolism in enterococcus faecalis studied by transcriptome, proteome and metabolome approaches
(PhD Thesis;2011:48, Doctoral thesis, 2011)Lactic Acid Bacteria (LAB) are widely used as starter culture in food fermentation. Among LAB also pathogenic bacteria are found particular in enterococci and streptococci. Enterococcus faecalis is a gut commensal bacterium ... -
Stress responses of Listeria monocytogenes to antimicrobial substances from lactic acid bacteria : an explorative study
(PhD Thesis;2011:02, Doctoral thesis, 2011)Listeria monocytogenes is a gram-positive bacterium that causes severe and life threatening disease both in humans and animals. Due to the severity of the disease and the fact that the bacterium is responsible for considerable ...
