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 ... -
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 ... -
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 ... -

Multivariate analysis as a tool for understanding and reducing complexity of mathematical models in systems biology
(PhD Thesis;2011:34, Doctoral thesis, 2011)In the area of systems biology, technologies develop very fast, which allows us to collect massive amounts of various data. The main interest of scientists is to receive an insight into the obtained data sets and discover ... -
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 ... -
Identification of androstenone sensitive subjects and their evaluation of different androstenone and skatole tainted meat products
(PhD Thesis;2011:12, Doctoral thesis, 2011)Castration of entire male pigs is widely used in Norway to prevent the unpleasant odour/flavour that may occur in meat from boars. Castration of entire male pigs is expected to be prohibited in Norway (and in Europe) in ... -
