ABSTRACT:
The present invention provides an enhanced biodegradation process by applying to petroleum contaminated soil or water essential microbial nutrients in a form capable of releasing the nutrients over time at a rate which, at 25.degree. C., is substantially linear. Importantly, in a preferred embodiment of the present invention, the microbial nutrients that are applied to the soil or water are in a form such that the release of nutrients at 38.degree. C. will be greater than that at 25.degree. C. by a factor of about 2.5 to 6.0, and preferably from a factor of about 3 to about 5.0.
