The presence of polychlorinated biphenyls (PCBs) in different natural matrices and consequent toxic effects represent a public health issue. Due to their bioaccumulation, they have negative effects on different living organisms, including humans. Here we report a preliminary investigation of suitability of a microalgae-based technique for the bioremediation of marine sediment and water column. Phaeodactylum tricornutum, a model benthic diatom is tested for removal of different biphenyl molecules from sea water solutions. Moreover, cells are individually modified with a polydopamine coating, to enhance both their resistance in harsh environmental conditions and the capability of remediation to hydrophobic pollutants.

Abstract
The presence of polychlorinated biphenyls (PCBs) in different natural matrices and consequent toxic effects represent a public health issue. Due to their bioaccumulation, they have negative effects on different living organisms, including humans. Here we report a preliminary investigation of suitability of a microalgae-based technique for the bioremediation of marine sediment and water column. Phaeodactylum tricornutum, a model benthic diatom is tested for removal of different biphenyl molecules from sea water solutions. Moreover, cells are individually modified with a polydopamine coating, to enhance both their resistance in harsh environmental conditions and the capability of remediation to hydrophobic pollutants.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
