Investigation of the release of PAHs from artificially contaminated sediments using cyclolipopeptidic biosurfactants

- The sorption of a mixture of PAHs was studied at the sediment/water interface.
- Clay and organic matter fractions were the most influent factors on PAHs sorption.
- Desorption of PAHs by cyclolipopeptidic (CLP) biosurfactants was investigated.
- Release of 2-4 ring PAHs from kaolinite was favored by adding SDS or amphisin.
- Amphisin and viscosin-like were effective to release low weight PAHs from sediments.
