DNA methylation in a nutritional and social context : a study of cytosine modifications in honey bee (Apis mellifera) workers
(PhD Thesis;2023:10, Doctoral thesis, 2023)Intergenic DNA methylation is widespread in both the animal and plant kingdoms. Its presence in exons is believed to be dynamic and suggests its involvement in the regulation of alternative splice variants. In addition, ... -
Objective methods of classification for beef- and pork carcases as a basis for evaluation of carcase yield
(PhD Thesis;2024:13, Doctoral thesis, 2024)Yield within the meat industry refers to the ratio and weight of tissues from the carcase. Carcase classification gives each carcase grades that determine the price paid for the carcase. Two aspects are especially important ... -
Exploring variability of perceptions and heterogeneity of opinions
(Dr. Philos. thesis;2023:2, Doctoral thesis, 2023)The manuscripts in this thesis introduce new sensometric methods. Some methods investigate the variability of perceptions in sensory studies involving trained or consumer panels. Other methods explore the heterogeneity of ... -
An investigation of the interplay between in situ hydrogen peroxide production and catalytic efficiency in lytic polysaccharide monooxygenase reactions
(PhD thesis;2022:27, Doctoral thesis, 2022)Lytic polysaccharide monooxygenases (LPMOs) are mono-copper enzymes that catalyze oxidative depolymerization of recalcitrant carbohydrate substrates, such as chitin and cellulose. LPMOs have received much attention from ... -
Bacteriocins : from discovery to characterization and applications
(PhD thesis;2023:74, Doctoral thesis, 2023)Multidrug resistant bacteria have become a major concern in both human and veterinary medicine. Due to the waning efficacy of many antibiotics, new antimicrobial agents are needed. Bacteriocins are ribosomally ... -
Local food entrepreneurs in Norway : case studies on successful practices for network learning and market development
(PhD Thesis;2023:23, Doctoral thesis, 2023)Local food has been compared to a "quiet culinary revolution" in Norway, one initiated by a governmental strategy more than 20 years ago. The aim was to provide more local specialtiesꟷ"food and drink products with a ... -
The site-2-protease RseP as a novel antimicrobial target
(PhD Thesis;2023:22, Doctoral thesis, 2023)The discovery and development of antibiotics have revolutionized modern medicine. Today, several decades after the first patients were treated with antibiotics, bacterial infections are again becoming increasingly difficult ... -
Cheese-making efficiency affected by protein source in concentrate feed for dairy cows and their αS1-κ-casein genotypes
(PhD Thesis;2023:32, Doctoral thesis, 2023)Evaluation of cheese-making efficiency is important for the dairy industry for profitability and sustainability reasons. Milk with a beneficial composition that favours good coagulation properties and a higher cheese yield ... -
Small intestinal microbiota – Regulation by reactive oxygen species and influence of diet
(PhD Thesis;2022:5, Doctoral thesis, 2022)Over the last years multiple studies have analyzed the impact of intestinal microbiota on health. Certain changes in the composition of the microbial population in the intestine have been associated with several diseases ... -
Leveraging H2O2-fuelled activity of lytic polysaccharide monooxygenases in cellulase cocktails for improved bioprocessing of lignocellulosic biomass
(PhD Thesis;2022:29, Doctoral thesis, 2022)Rapid action is critical to reduce anthropogenic CO2 emissions in order to reach climate targets. Fossil fuel use in high emission sectors like the energy and chemical industry should therefore be reduced and replaced by ... -
Development of Liquid Array Diagnostic (LAD) technology for prediction of human gut microbiota composition and functionality
(PhD Thesis;2022:13, Doctoral thesis, 2022)The microbial species residing in the human gut exercise vital functions for the host. They produce different metabolites that are crucial for human wellbeing. A variety of such molecules mediate signalling along the ... -
Impact of dietary components and reactive oxygen species (ROS) in the colon and its microbiota in a low-grade inflammation mouse model
(PhD Thesis;2022:58, Doctoral thesis, 2022)Background: Various factors, including dietary components, the gut microbiota and host responses, are imperative for gut health. Optimal interactions between diet, gut microbiota and host are suggested to be important to ... -
Light-driven lytic polysaccharide monooxygenase (LPMO)-catalyzed solubilization of polysaccharides
(PhD Thesis;2022:38, Doctoral thesis, 2022)Lytic polysaccharide monooxygenases (LPMOs) are a recently discovered family of enzymes that catalyze oxidative cleavage of glycosidic bonds in insoluble polysaccharides at a liquid-solid interface. These enzymes are ... -
Understanding and optimizing the role of lytic polysaccharide monooxygenases in enzymatic conversion of lignocellulosic biomass
(PhD Thesis;2022:31, Doctoral thesis, 2022)Lignocellulosic biomass holds great potential for production of biofuels and other chemicals traditionally produced from fossil fuels. However, its significant recalcitrance presents a substantial challenge in industrial ... -
Relationship inference and inbreeding in forensic genetics
(PhD Thesis;2021:48, Doctoral thesis, 2021)Inference of relatedness between individuals is of interest in fields as disparate as animal breeding, archaeology, medical genetics and genealogy. In the forensic context, emphasised in this thesis, applications include ... -
