- Abstract
- The effect of soil contents and mass transfer rates on soil bioremediation was investigated. Phenanthrene, a 3-ring polycyclic aromatic hydrocarbon (PAH), was chosen as a model target compound. The biodegradation tests were performed in soil-slurry systems at two distinct mass transfer rates: fast in flasks tests at 150 rpm and slow in roller-bottle tests at 2 rpm. The rate of phenanthrene biodegradation was similar at low soil content (2 wt.%) in both slurry systems, but the rates at high soil contents (6 and 18 wt.%) were higher in the roller-bottle tests. The maximum utilization rate constant for sorbed-phase biodegradation obtained from curve fitting using a mathematical model was decreased in the flask tests with increasing soil content, while not decreased in the roller-bottle tests.
