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

http://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

http://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...

Legionella pneumophila in Norwegian naval vessels

http://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...

Biofilms from flow-cells - A model study with Pseudomonas aeruginosa, Confocal Laser Scanning Microscopy (CLSM) and metabolic fingerprinting

http://www.sintef.no/en/publications/publication/?pubid=SINTEF+S16981

Summary Metabolic fingerprinting by high resolution (TOF) MS can be used to identify both complex and specific changes in extracellular biofilm metabolite patterns. The potential of the method is demonstrated through significant changes in metabolite patterns as shown in Figure 3 as well as identif...
