Alginate gels cross-linked with mixtures of calcium and chitosan oligomers: Effect on swelling properties and leakage from the gel
(Master thesis, 2016)A new alginate gelling system was recently reported where chitosan oligomers were used to cross-link alginate (poly-M) (Khong et al., 2013). These results have been followed up by determining the gel strength and syneresis ... -
Conjugation to the chain termini of chitin oligosaccharides
(Master thesis, 2017)Today's polymer science is based largely on the creation of synthetic block copolymer structures. The possibility of creating block copolymer structures from biological polysaccharides with the same physiochemical properties ... -
Extracellular matrix modifications by oligoguluronates for cancer treatment
(Master thesis, 2018)Type I collagen is the main structural protein of the extracellular matrix, and is abnormally produced in many types of solid tumours. The presence of a thick and linearised collagen fibres constituting a dense network in ... -
Feeding Strategy and Effect on Fillet Quality of Atlantic Salmon (Salmo salar)
(Master thesis, 2016)This thesis seeks to explore how changes in feeding strategy can affect the fillet quality of farmed Atlantic salmon (Salmo salar). By changing the number of daily feedings or the degree of marine raw materials it will be ... -
Gel Beads of Alginate from Laminaria Hyperborea Leaf - Stability related to size and polymer distribution
(Master thesis, 2015)Alginate microbeads have through many years of research shown great potential as an immunoisolation system for the entrapment of insulin-producing cells. However, one of the main challenges in the use of alginate gels as ... -
Isolering og karakterisering av helsefremmende lipider fra mikroalger
(Master thesis, 2016)Langkjedete omega-3 fettsyrer, som EPA (eikosapentaensyre) og DHA (dokosahexaensyre), er viktige for et balansert kosthold og kan gi gode helsemessige fordeler. Per dags dato får de fleste for lite av disse fettsyrene ... -
Karakterisering av avfallsstrømmer i matindustri
(Master thesis, 2016)I næringsmiddelindustrien, som er en av verdens største industrier, generes store mengder biråstoffer og prosessvann under produksjon og flyten av avfallsstrømmene er svært stor. Det er flere betydelige miljøutfordringer ... -
Lavsaltprodukter av torsk (Gadus morhua) og laks (Salmo salar) - Betydningen av MgCl2 og MgSO4 på muskelproteiners løselighet og termiske stabilitet
(Master thesis, 2016)Salt (NaCl) er et av de mest anvendte konserveringsmidlene i matindustrien, noe som skyldes lave kostnader og saltets bidrag til smak og konservering. Det har imidlertid vist seg at en stor andel av befolkningen konsumerer ... -
Marine Cod (Gadus morhua) Head Hydrolysates - in vitro ACE inhibitory activity and investigation of structure-activity relationship
(Master thesis, 2018)Marine by-products contain valuable nutrients and there is an increasing interest in production of value-added products for human consumption. Cod (Gadus morhua) head hydrolysates produced by SINTEF Ocean in the pilot ... -
Metabolic Engineering of Bacillus methanolicus MGA3 for Production of Acetoin
(Master thesis, 2018)Being a pure, inexpensive, non-food chemical that can be sustainably produced, methanol has attracted great interest as a carbon feedstock for microbial production of commodity/specialty chemicals. In this thesis, ... -
Methodology for Determination of Degree of Hydrolysis
(Master thesis, 2015)Abstract The utilization of rest raw materials is becoming increasingly important due to the increasing demand for marine food sources. One way to do this is by enzymatic hydrolysis of the rest raw material from fish. ... -
Penetrating the Mucus Barrier - The Effect of Addition of Guluronate Oligomers on the Mobility of Nanoparticles in Porcine Small Intestinal Mucus
(Master thesis, 2015)Oral delivery is the easiest and most used method of drug delivery. However, the gastrointestinal (GI) tract poses many hurdles for the drugs to overcome before they can reach their target. One of them is the viscous, ... -
Robustness of nitrifying biofilter functionality: Role of competition between heterotrophic and nitrifying bacteria on ammonium removal efficiency and microbial community structure
(Master thesis, 2017)Removal of ammonium by nitrification in biofilm systems is a common method in wastewater treatment. The ammonium removal efficiency in the nitrification process is influenced by the competition between nitrifying bacteria ... -
Strategies for Stabilising Calcium Alginate Gel Beads: Studies of Chitosan Oligomers, Alginate Molecular Weight and Concentration
(Master thesis, 2017)Microencapsulation of cells or tissues in alginate-based capsules is the most commonly applied technique for immunoisolation. However, the biocompatibility of the capsules and their long-time stability under physiological ... -
The Effect of Alginate G-block Treatment on the Extracellular Matrix
(Master thesis, 2018)Dense extracellular matrix and alterations of extracellular matrix are two of the hallmarks of solid tumors. The resulting highly fibrotic extracellular matrix is associated with several types of cancer. These solid tumors ... -
Towards Dextran-Based Block Polysaccharides
(Master thesis, 2018)Carbohydrates covalently linked with other chemical species are termed glycoconjugates. They are important compounds in biology, and are involved in many processes, such as cell-cell interactions. Glycoconjugates can be ... -
Towards Polysaccharide Origami: Preparation of Chitooligosaccharide-Dihydrazide Hybrids
