Biocomposites prepared by alkaline phosphatase mediated mineralization of alginate microbeads
(Journal article; Peer reviewed, 2012)This study set out to develop a biomimetic scaffold by incorporating osteoinductive hydroxyapatite (HA) particles into a porous alginate gel matrix via a cell-friendly pathway. Two types of alginate/calcium phosphate ... -
Biofilms remember: Osmotic stress priming as a microbial management strategy for improving salinity acclimation in nitrifying biofilms
(Peer reviewed; Journal article, 2020)With increasing freshwater scarcity and greater use of seawater,fluctuating salinities are becomingcommon in water treatment systems. This can be challenging for salinity-sensitive processes like nitri-fication, especially ... -
Biogeochemistry of iron in Patagonian fjords and waters of the Antarctic Peninsula
(Doctoral theses at NTNU;2017:191, Doctoral thesis, 2017)Iron constitute an essential nutrient for marine life. Several metabolic processes in marine phytoplankton, are dependent on the presence of this trace element. Due to the chemistry of seawater, in certain marine ... -
Biokatalytisk oksidasjon av limonen
(Master thesis, 2020)I denne litteraturstudien diskuteres ulike oksidasjoner av limonen katalysert av en rekke biokatalysatorer. Fokuset er spesielt på biotransformasjoner katalysert av cytokrom P450 enzymer, både som rene, isolerte enzymer, ... -
Biological reductions and esterifications for the production of enantiopure secondary alcohols : chemo-enzymatic synthesis of chiral building blocks with sulphur-containing rings
(Doktoravhandlinger ved NTNU, 1503-8181, Doctoral thesis, 2003)Both enantiomers of 1-(1,3-dithian-2-yl)-2-propanol ( 5 ) 1-(1,3-dithiolan-2-yl)-2- propanol (6), and halogenated derivatives of 5 was obtained by microbial reductions and lipase catalyzed esterifications. (2S)-1-(1,3-di ... -
Biotic transformation of methylmercury at the onset of the Arctic spring bloom
(Journal article; Peer reviewed, 2024)Despite the lack of local anthropogenic mercury sources, methylated mercury (MeHg) concentrations in Arctic biota are higher than in biota from lower latitudes. The main entry route occurs during the bioconcentration of ... -
