Biodegradation of phenanthrene was studied in soil slurry reactors in the presence and absence of a surfactant solution. Results showed that the presence of surfactants slowed the initial biodegradation rate of phenanthrene, but increased the total mass of phenanthrene degraded over a four day period by 30%. A mathematical model was developed to simulate the dynamics of the biodegradation of low solubility hydrocarbons in the presence of soils and surfactants. Processes such as the desorption kinetics of the hydrocarbon from soil, the sorption of the surfactant onto soil and its effect on the sorption of the hydrocarbon, and the bioavailability of the hydrocarbon in different phases of the system are included in the model formulation. The experimental results were measured independently. The model was used to investigate the effect on the overall biodegradation of phenanthrene due to different operating conditions. simulation results showed that there is a system-specific optimum surfactant concentration, above which bioremediation is hindered.

Bacterial isolates from soils contaminated with a large range of organic pollutants were tested for their ability to metabolise selected recalcitrant PAHs as their sole energy and carbon source. Plating of soil microorganisms isolated from 12 petroleum-contaminated soils on solid medium, supplemented with the PAH phenanthrene as sole carbon source, yielded 228 phenanthrene-degrading bacterial strains, of which 60 were further characterized. Southern DNA-DNA hybridization identified 14 of the 60 colonies as potentially competent in naphthalene degradation (ndoB Positive). The 14 bacterial isolates were further screened for their capacity to mineralize six radiolabelled PAHs serving as their sole carbon and energy source. Under such conditions, bacterial isolate strain S65 cumulatively mineralized 61% of phenanthrene, 61% of pyrene, and 24% of fluoranthene over a 9-day period, but could not degrade naphthalene, anthracene or fluorene.Three different ...
