Acid preservation of cultivated brown algae Saccharina latissima and Alaria esculenta and characterization of extracted alginate and cellulose
Nøkling-Eide, Katharina; Tan, Fangchang; Wang, Shennan; Zhou, Qi; Gravdahl, Mina; Langeng, Anne-Mari; Bulone, Vincent; Aachmann, Finn Lillelund; Sletta, Håvard; Arlov, Øystein (Peer reviewed; Journal article, 2023)Cultivated brown algae represent an important potential source of carbohydrate polymers for packaging and other biobased materials. However, their exploitation is currently limited by a short harvest season and a lack of ... -
An assessment of physical and chemical conditions in alginate extraction from two cultivated brown algal species in Norway: Alaria esculenta and Saccharina latissima
Nøkling-Eide, Katharina; Langeng, Anne-Mari; Åslund, Karl Olof Andreas; Aachmann, Finn Lillelund; Sletta, Håvard; Arlov, Øystein (Peer reviewed; Journal article, 2023)Alginates are linear anionic polysaccharides originating from brown algae. Their properties target several application areas in in food-, technical- and pharmaceutical industries, and thus they are highly valued. Norway ... -
Biomimetic sulphated alginate hydrogels suppress IL-1B-induced inflammatory responses in human chondrocytes
Arlov, Øystein; Öztürk, E.; Steinwachs, M.; Skjåk-Bræk, Gudmund; Zenobi-Wong, M. (Journal article; Peer reviewed, 2017)Loss of articular cartilage from ageing, injury or degenerative disease is commonly associated with inflammation, causing pain and accelerating degradation of the cartilage matrix. Sulphated glycosaminoglycans (GAGs) are ... -
Bioprinting of functionalized alginate-nanocellulose scaffolds for 3D cultivation of human dermal fibroblasts
Aarseth, Ingrid Weløy (Master thesis, 2022)Nye systemer for 3D-cellekultivering har blitt forsket på for å forbedre in vitro mikromiljø for celler. Målet til disse systemene er å danne et fysiologisk representativt miljø for cellekulturer slik at man kan undersøke ... -
Characterization of Sulfated Alginate Hybrid Gels for Tissue Engineering
Aaen, Ragnhild (Master thesis, 2015)Tissue engineering is a field aiming to replace damaged tissue while reducing the great need of organ donors the world is facing today. Alginates are linear co-polymers consisting of the two monosaccharides β-D-mannuronic ... -
Extraction, Characterization, and Biological Activities of Laminarin and Fucoidan from Laminaria hyperborea
Henriksson, Emilia Linnea (Master thesis, 2019)Fucoidan og laminaran finnes som biprodukter i sidestrømmer som stammer fra alginatproduksjon. Utnyttelse av restråstoff fra tare kan generere produkter av kommersiell verdi, og dermed føre til økonomisk vekst for ... -
Heparin Analogs Created by Sulfation of Alginates Using a Chemoenzymatic Strategy
Arlov, Øystein (Master thesis, 2012)Alginates are a class of natural unbranched linear polysaccharides, and consist of the monomers β-D-mannuronic acid and α-L-guluronic acid. The inherent physical properties, relative ease of modification, wide availability ... -
Sulfated alginate microspheres associate with factor H and dampen the inflammatorycytokine response
Arlov, Øystein; Skjåk-Bræk, Gudmund; Rokstad, Anne Mari (Journal article; Peer reviewed, 2016)Alginate microspheres show promise for cell-encapsulation therapy but encounter challenges related to biocompatibility. In the present work we designed novel microbeads and microcapsules based on sulfated polyalternating ... -
Sulfated Alginates as Heparin Analogues: A Review of Chemical and Functional Properties
Arlov, Øystein; Skjåk-Bræk, Gudmund (Journal article; Peer reviewed, 2017)Heparin is widely recognized for its potent anticoagulating effects, but has an additional wide range of biological properties due to its high negative charge and heterogeneous molecular structure. This heterogeneity has ... -
SULFATED ALGINATES: Characterization and applications as biomaterials
Arlov, Øystein (Doctoral thesis at NTNU;2016:159, Doctoral thesis, 2016)As natural constituents of the extracellular matrix, sulfated glycosaminoglycans (GAGs) are of great interest in the design of novel biomaterials for cell immobilization and tissue engineering. A substantial challenge ...
