Little is known about the degrading flora present during the bioremediation process for treatment of polycyclic aromatic hydrocarbons (PAHs). The characterization of bacteria present would greatly enhance ongoing studies which are underway at Rice University. The goal of the proposed research was to quantify and characterize microorganisms in sediment samples contaminated with PAHs (Fluorene or phenathrene). Specific research objectives were:
The isolated organisms were evaluated for their ability to degrade PAHs compounds (fluorene or phenathrene). The results will support current research at Rice University (Houston), e.g. isolates can be applied in situ bioremediation experiments. The goal of the project was to quantify and characterize microorganisms in sediment samples contaminated with polycylic aromatic hydrocarbons (PAHs: phenathrene, fluorene, and naphthalene). The isolated organisms were evaluated for their ability to degrade PAHs compounds.
