Protein fractionation by microfiltration in high-protein yogurt processing
(PhD Thesis;2017:58, Doctoral thesis, 2017)The main objective of the work presented in this thesis was to investigate the optimization of the microfiltration (MF) process in the production of high-protein yogurts (≥ 5.6% protein). High-protein yogurts have gained ... -
Novel aspects of the ecophysiology of denitrifying bacteria and their roles in N2O emissions
(PhD Thesis;2017:91, Doctoral thesis, 2017)Environmental bacteria are in general limited by nutrient availability, and as the conditions fluctuate rapidly and unpredictably they must adapt or they will not thrive. This requires fast and adequate sensing and ... -
Structural and functional characterization of NcLPMO9C : a broad-specificity lytic polysaccharide monooxygenase
(PhD Thesis;2017:93, Doctoral thesis, 2017)Lignocellulose represents a major source of renewable organic matter and is of interest as feedstock for the biorefining industry, not only as a promising strategy for replacing fossil fuels in the transportation sector ... -
Parameters and pedigrees in forensic genetics and statistics
(PhD Thesis;2017:46, Doctoral thesis, 2017)With the rapidly evolving DNA technology today, there is a constant need of more robust statistical methods for analyzing the data. The sequencing techniques are improving, making more genetic markers available, and we are ... -
Degradation of proteinaceous material, ammonium accumulation and microbial dynamics in anaerobic digesters
(PhD Thesis;2017:83, Doctoral thesis, 2017)Anaerobic digestion (AD) of organic material from Norwegian farms can contribute to the agricultural value chain. Agricultural waste, including animal manure, is in large supply in Norway and AD of these fractions can ... -
Microbial denitrification control in acid and neutral soils with implications for greenhouse gas emissions and atmospheric chemistry
(PhD Thesis;2017:51, Doctoral thesis, 2017)As with the ancient philosophy of ex nihilo, nihil fit (out of nothing, nothing is produced: nothing comes from nothing), the law of the conservation of mass dictates that no atoms in a chemical reaction may be created or ... -
Investigating evolution of gene regulation with crossspecies comparative transcriptomics
(PhD Thesis;2017:101, Doctoral thesis, 2017)An essential ability of all lifeforms is to regulate the activity of its genes. This ability is what allows multicellular organisms to generate hundreds of completely different cells despite having the same genome. It is ... -
Discovery and characterization of enzymes acting on chitin
(PhD Thesis;2017:71, Doctoral thesis, 2017)In the shift from a fossil-based to a bio-based economy, exploration of renewable recourses is needed. Chitin is considered the second most abundant polysaccharide on Earth, after cellulose, and its water-soluble derivatives ... -
The Soil Bacterium Methylococcus capsulatus Bath and its Interactions with Human Immune Cells in vitro
(PhD Thesis;2017:94, Doctoral thesis, 2017)Whereas a role for commensal microbes in the development and normal function of the immune system is well established, a potential role for environmental bacteria in regulating immunity has been widely disregarded. However, ... -
Total synthesis as a tool for structural elucidation of some marine lipid natural products
(PhD Thesis;2017:32, Doctoral thesis, 2017)Paper I describes the total synthesis of the proposed structure of mucosin, a C20 fatty acid, isolated from a Mediterranean sponge, Reniera mucosa. The synthetic pathway started with the transformation of 1,4-cyclohexadiene ... -
Evaluating nuclear magnetic resonance (NMR) as a robust absolute reference method for water holding capacity (WHC) of pork meat
(PhD Thesis;2016:64, Doctoral thesis, 2017-01-05)Water holding capacity (WHC) is among the most important quality traits of meat. However, the mechanism behind WHC continues to be poorly understood and online measurement has yet to be achieved in the meat industry. The ... -
Impact of milk protein genotypes on milk coagulation properties
(PhD Thesis;2017:74, Doctoral thesis, 2017-08-21)Evaluation of the milk coagulation properties is very important for the dairy industry, because it gives information on the processability of milk for both cheese and yoghurt/cultured milk. Milk that takes a shorter time ... -
The microbial diversity of mesophilic starter cultures used in cheese production
(PhD Thesis;2017:96;, Doctoral thesis, 2017-11)For ages, humankind has preserved various foods by fermentation by lactic acid bacteria (LAB), and fermentation of milk to obtain cheese can be traced back to the domestication of cattle, at least seven millennia ago. ... -
Fungal aerosols : characterization and immunodetection of fungal fragments
(PhD Thesis;2015:26, Doctoral thesis, 2017-11-30)Indoor environments with high moisture problems often reveal colonization of indoor materials by fungi with release of airborne fungal particles. Exposure to airborne fungal particles has been associated with various ... -
Factors influencing the processing quality of potatoes : development of analytical tools for process monitoring and optimization
(PhD Thesis;2015:30, Doctoral thesis, 2017-11-30)Potatoes are notoriously heterogeneous, and manufacturers of processed potato products are therefore faced with a number of challenges during processing. The motivation behind this thesis is to reduce waste and cut production ... -
Staphylococcus aureus from milk and milk products in Ethiopia : prevalence, enterotoxigenic potential, antibiotic resistance and spa types
(PhD Thesis;2016:48, Doctoral thesis, 2017-12-12)Milk production in Ethiopia is increasing. However, due to unhygienic and traditional milk production and processing practices the issue of milk safety remains a challenge. If these safety issues are not properly addressed, ... -
