Interaction between microalgae, marine snow and anionic polyacrylamide APAM at marine conditions

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1757531

When an oil field ages and the pressure in the reservoir decreases, or for oil fields with heavy oil, there may be a need for enhanced oil recovery (EOR) technologies. Polymer injection is a water-based EOR method where the viscosity of the water injected for pressure support is increased by mixing ...

Effects of produced water on pelagic marine organisms - Focus on the copepod Calanus finmarchicus - OC2017 A-121

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1474839

The main aim of this project was to provide a basis for assessing the potential health effects of produced water (PW) on the marine pelagic zooplankton Calanus finmarchicus in the field. This report describes three experiments assessing the impact of reconstituted PW extracts on copepod PAH body res...

Rapid metabolic profiling of developing Pseudomonas aeruginosa biofilms by high-resolution mass spectrometry fingerprinting

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1140055

Biofilms are single- or multi-species communities of bacteria that are enclosed in an extracellular matrix. These cells generally exhibit phenotypes that are significantly different from those of planktonic cells, yet detailed elucidation of the causality and the exact nature of this metabolic shift...

Membranfiltrering av bakterien Moritella viscosa fra sjøvann

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1510833

Bakterien Moritella viscosa forårsaker sykdommen vintersår hos laks og kan føre til stor dødelighet hos smolt i sjøvann og sår hos laks som fører til nedklassing ved slakt. I tillegg til økonomiske tap er også sykdommen et velferdsproblem for fisken. Pros...

Legionella pneumophila in Norwegian naval vessels

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1067787

BACKGROUND Little is known about the occurrence of Legionella pneumophila in water supply systems on board ships. Our aim was to study the occurrence of L. pneumophila in the water supply system on board Norwegian naval vessels as the basis for framing preventive strategies against Legionella infect...
