Kefir and kefir grains : diversity of chemical properties and microflora
(PhD Thesis;2012:30, Doctoral thesis, 2012)Kefir grains contain bacteria and yeasts embedded in a protein and polysaccharide matrix. They constitute the primary starter culture for kefir, a fermented milk drink with a complex sensory profile containing high amounts ... -
Kinetic investigations of the oxidative cleavage of oligomeric carbohydrates provide novel insights into the catalytic action of fungal lytic polysaccharide monooxygenases
(PhD Thesis;2021:61, Doctoral thesis, 2021)The lytic polysaccharide monooxygenases (LPMOs) are a recently discovered class of redoxactive mono-copper enzymes that catalyze the oxidative cleavage of glycosidic bonds in recalcitrant plant or chitin-based biomass, ... -
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 ... -
Lactobacillus sakei metabolism and diversity
(PhD Thesis;2010:21, Doctoral thesis, 2010)Lactic acid bacteria are associated with food fermentation, acidification and preservation. Lactobacillus sakei is an industrially important species mainly due to its ability to ferment and preserve meat. It is used as ... -
Langtransport og avsetning av organiske miljøgifter i nordvestlige Europa
(PhD Thesis;2014:90, Doctoral thesis, 2015-02-16)Persistent organic pollutant (POPs) are toxic compounds which typically consist of one or more groups of hydrocarbons that are aromatic or aliphatic as well as halogenated (chlorine, bromine, fluorine). POPs are normally ... -
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 ... -
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 ... -
Linear multiresponse models : theoretical developments and applications in porcine
(PhD Thesis;2016:34, Doctoral thesis, 2018-05-03)The main topic of this PhD–thesis is how to minimize the prediction error for multi–response linear regression models. Two different applications are analysed, (i) bivariate response with missing data and (ii) image analysis ... -
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 ... -
Microbial communities in biogas reactors and their link to stability and performance
(PhD Thesis;2016:60, Doctoral thesis, 2020-11-24)The Anaerobic digestion (AD) of organic material gathers a great interest worldwide due to the global needs for waste recycling and renewable energy production. Biogas, the end product of an AD process, is a mixture of ... -
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 ... -
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. ... -
Minimizing photooxidation in dairy products by tailor made light barrier properties in packaging materials
(PhD Thesis;2011:47, Doctoral thesis, 2011)Photooxidation is one of the major causes of food quality deterioration. Packaging is a common tool to protect against light and consequently prolong the shelf life of food. Transparent packaging materials are being widely ... -
Mitochondrial oxygen consumption and myoglobin redox stability in beef
(PhD Thesis;2012:14, Doctoral thesis, 2012)Myoglobin is the main pigment in meat and exists in three predominant states; deoxymyoglobin (DMb), oxymyoglobin (OMb), and metmyoglobin (MMb). The different myoglobin states are dependent on the production of mitochondrial ... -
Modern sour beer production : mixed fermentations with yeast and lactic acid bacteria
(PhD Thesis;2019:104, Doctoral thesis, 2019)Traditional sour beers are produced by spontaneous, mixed fermentations where numerous yeast and bacterial species are involved. One of the traits that separate sour beers from other beers is the high concentration of ... -
