Biotransformation of chemically dispersed diesel at sub-zero temperatures using artificial brines.

The biotransformation of hydrocarbon compounds in seawater at sub-zero temperature has gained research interest in recent years with the most focus placed on temperatures around 0°C. In this study, biotransformation of dispersed diesel at sub-zero temperatures (-2°C to -6°C) in artificial brines, prepared by adding Instant Ocean salt to natural seawater to increase salinity, is examined. The oil was pre-mixed with dispersant Finasol 51 to prepare the dispersed oil at 2 mg l.
