Biodegradation of oil spill dispersant surfactants in cold seawater
Brakstad, Odd Gunnar; Størseth, Trond Røvik; Brunsvik, Anders; Bonaunet, Kristin; Faksness, Liv Guri (Journal article; Peer reviewed, 2018)While biodegradation of chemically dispersed oil has been well documented, only a few studies have focused on the degradation of the dispersant compounds themselves. The objective of this study was to determine the ... -
Combined analytical strategies for chemical and physical characterization of tar from torrefaction of olive stone
Trubetskaya, Anna; Johnson, Robert; Monaghan, Rory F. D.; Ramos, Andrezza S.; Brunsvik, Anders; Wittgens, Bernd; Han, Yinglei; Pisano, Italo; Leahy, James J.; Budarin, Vitaliy L. (Peer reviewed; Journal article, 2021)The advance in analytical methodology is critical for progress in 1) biorefinery and 2) torrefaction product commercialization. The chemical characterisation of torrefaction liquid and concentrated tar produced by Arigna ... -
Demonstration of a novel instrument for online monitoring of absorber emissions to air
Einbu, Aslak; Hjarbo, Kai Wilhelm; Brunsvik, Anders; Zahlsen, Kolbjørn; Wittgens, Bernd (Peer reviewed; Journal article, 2021)A novel concept for online monitoring of nitrosamines, solvent amines and their degradation products in amine absorber emissions to air was demonstrated at the Tiller CO2-lab pilot facility. The monitoring concept is based ... -
Effects of Lignin Gasification Impurities on the Growth and Product Distribution of Butyribacterium methylotrophicum during Syngas Fermentation
Pacheco, Marta; Pinto, Filomena; Brunsvik, Anders; André, Rui; Marques, Paula; Mata, Ricardo; Ortigueira, Joana; Gírio, Francisco; Moura, Patrícia (Peer reviewed; Journal article, 2023)This work evaluated the effects of condensable syngas impurities on the cell viability and product distribution of Butyribacterium methylotrophicum in syngas fermentation. The condensates were collected during the gasification ... -

Iodinin (1,6-dihydroxyphenazine 5,10-dioxide) from streptosporangium sp. induces apoptosis selectively in myeloid leukemia cell lines and patient cells
Myhren, Lene Elisabeth; Nygaard, Gyrid; Gausdal, Gro; Sletta, Håvard; Teigen, Knut; Degnes, Kristin Fløgstad; Zahlsen, Kolbjørn; Brunsvik, Anders; Bruserud, Øystein; Doskeland, Stein Ove; Selheim, Frode; Herfindal, Lars (Journal article; Peer reviewed, 2013)Despite recent improvement in therapy, acute myeloid leukemia (AML) is still associated with high lethality. In the presented study, we analyzed the bioactive compound iodinin (1,6-dihydroxyphenazine 5,10-dioxide) from a ... -
Microencapsulation of Peppermint Oil by Complex Coacervation and Subsequent Spray Drying Using Bovine Serum Albumin/Gum Acacia and an Oxidized Starch Crosslinker
Glomm, Wilhelm Robert; Molesworth, Peter Patrick; Sandru, Eugenia-Mariana; Truong, Thuy le; Brunsvik, Anders; Johnsen, Heidi (Peer reviewed; Journal article, 2021)Most liquid food flavours such as essential oils are volatile and prone to degradation in the presence of oxygen, light, moisture and high temperatures. Microencapsulation of volatile ingredients prior to use in food or ... -
Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears
Tartu, Sabrina; Lille-Langøy, Roger; Størseth, Trond Røvik; Bourgeon, Sophie; Brunsvik, Anders; Aars, Jon; Goksøyr, Anders; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Routti, Heli (Journal article; Peer reviewed, 2017)There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for ... -

The organosolv lignins were ... -
Using machine learning-based variable selection to identify hydrate related components from FT-ICR MS spectra
Gjelsvik, Elise Lunde; Fossen, Martin; Brunsvik, Anders; Tøndel, Kristin (Peer reviewed; Journal article, 2022)The blockages of pipelines caused by agglomeration of gas hydrates is a major flow assurance issue in the oil and gas industry. Some crude oils form gas hydrates that remain as transportable particles in a slurry. It is ...
