Summary:The oleophilic fertilizer Inipol EAP 22 and microbial biosurfactant rhamnolipid were investigated for their ability to increase the rate of biodegradation of aliphatic and aromatic hydrocarbons by pure bacterial cultures. Pseudomonas putida, P. oleovorans and an unknown naphthalene degrading strain were used in the biodegradation experiments. Results suggest that increasing the bioavailability of hydrocarbons to bacteria may be a useful method for accelerating the rate of biodegradation at contaminated sites. Furthermore, the hypothesis that surface active components present in the oleophilic fertilizer formulation may have significantly contributed to the positive results reported in tests of remedial agent impact in bioremediation.
