Back to basics : simplifying microbial communities to decrypt complex interactions
(PhD Thesis;2020:33, Doctoral thesis, 2020)Microbes are everywhere and contribute to many essential processes relevant for planet Earth, ranging from biogeochemical cycles to complex human behavior. The means to achieve these colossal tasks for such small and, at ... -
Non-target and suspect characterisation of organic chemicals of emerging concern in air and biota
(PhD Thesis;2020:42, Doctoral thesis, 2020)Persistent organic pollutants (POPs) and other regulated organic chemicals are being monitored in the environment to evaluate the effectiveness of regulations and conventions, spatial and temporal trends as well as a ... -
Characterization of heteropathogenic and multidrugresistant (MDR) bacterial isolates from clinical and environmental sources using combined nanopore and next-generation sequencing technologies
(Doctoral thesis, 2020)Escherichia coli (E. coli) are usually harmless commensals that colonize the gastrointestinal tract of humans and other warm-blooded mammals. However, pathogenic counterparts have acquired virulence associated genes (VAGs) ... -
Production and characterisation of native whey and native whey products
(PhD Thesis;2016:15, Doctoral thesis, 2020-10-27)When microfiltration is applied in order to casein-standardise cheese milk, native whey (skimmed milk microfiltration permeate) is generated. Native whey consists of minor serum components that are allowed to be transmitted ... -
Quality changes in lamb/sheep and beef meat related to oxidative processes in muscle systems
(PhD Thesis;2015:77, Doctoral thesis, 2020-11-10)The oxidative processes in meat post mortem maintain the formation of free radicals. Behavior of reactive oxygen species is closely related to the energy metabolism of the muscle cell, mitochondrial activity and efficiency ... -
Cheese intake and risk factors for cardiovascular diseases and the metabolic syndrome : with particular reference to Gamalost intake and its effect on blood pressure
(PhD Thesis;2015:23, Doctoral thesis, 2020-11-10)The papers included in this thesis are part of a larger project titled “Healthy Cheese” (SUNN OST), with an overall main objective to establish a platform to develop innovative and healthy cheese varieties with reduced fat ... -
Establishment of gut microbiota in infants from a large Norwegian cohort
(PhD Thesis;2015:76, Doctoral thesis, 2020-11-10)Human gut microbiota, our so-called forgotten organ, is crucial for proper functioning of our body and for health maintenance. Although the topic of the gut microbiota establishment is very important, scientists still have ... -
Present health challenges in fresh and processed meat
(PhD Thesis;2016:28, Doctoral thesis, 2020-11-13)Processed meat intake is claimed to involve a higher risk of colon cancer. In particular, sausage intake is high and therefore has a potential for influencing consumers’ health. In Norway, sausage consumption has been ... -
Computational challenges in family genetics
(PhD Thesis;2015:36, Doctoral thesis, 2020-11-13)There is a constant demand to determine the most probable relationship between a set of person given some genetic marker data and some hypotheses about pedigree structure. A constant stream of paternity cases is obtained ... -
Syntheses of 3-, 4- and 5-membered carbocycles : new methodology on old methods
(PhD Thesis;2015:94, Doctoral thesis, 2020-11-13)The main focus of this thesis was to use new methodology on already well-established methods of preparation of 3-membered, 4-membered and 5-membered carbocyclic compounds with the emphasis on improving them. Traditional ... -
