Popis: | Polycyclic aromatic hydrocarbons have a low water solubility and tend to adsorb on soil particles, which both result in slow bioremediation processes. Many microorganisms, known for their ability to degrade polycyclic aromatic hydrocarbons, only partially oxidize these compounds. White rot fungi, for instance, convert polycyclic aromatic hydrocarbons to more water soluble and bioavailable products. Polycyclic aromatic hydrocarbon metabolites were more readily mineralized by natural mixed bacterial cultures, like activated sludge and soil, than the parent polycyclic aromatic hydrocarbon compounds. These results suggest that sequential breakdown by white rot fungi followed by indigenous bacteria leads to an effective polycyclic aromatic hydrocarbon bioremediation process. |
