Abstract:

Biodegradation of crude oil in seawater (SW) is mainly associated with small droplet dispersions and solubilized compounds. Efficient treatment of oil spills with chemical dispersants may therefore enhance oil biodegradation. At SINTEF, we have performed biodegradation studies of chemically dispersed oil, but also with oil immobilized to hydrophobic adsorbents. A variety of studies have been performed with oils of different properties, local SW with different temperatures, as well as SW from different sources. Lately, the studies have also included biodegradation of aggregated oil (oil-related marine snow), as well as studies in frazil and solid marine ice. The studies have included both determinations of biotransformation rates and microbial communities associated with degradation. The work performed has mainly been conducted in close collaboration with the Norwegian University of Science and Technology (NTNU)
