dc.description.abstract | Recalcitrant polycyclic aromatic hydrocarbons (PAHs) released into seawater end up in the deep sea sediments (DSSs). However, their fate here is often oversimplified by theoretical models. Biodegradation of PAHs in DSSs, is assumed to be similar to biodegradation in surface habitats, despite high hydrostatic pressures and low temperatures that should significantly limit PAH biodegradation. Bacteria residing in the DSSs (related mainly to α- and γ- Proteobacteria) have been shown to or predicted to possess distinct genes, enzymes andmetabolic pathways, indicating an adaptation of these bacterial communities to the psychro-peizophilic conditions of theDSSs. Thiswork summarizes some of the most recent research on DSS hydrocarbonoclastic populations andmechanisms of PAH degradation and discusses the challenges posed by future high CO2 and UV climate scenarios on biodegradation of PAHs in DSSs. | pt |
