Abstract
An integration of a natural biodegradation half-life model and oil toxicity model has resulted in a precise, fine-tuned science-based technology for evaluating success of bioremediation strategies, particularly for crude oil-contaminated soil. By extension, this mathematical tool can be applied for impact assessment of crude oil on land at a given time. This Methods paper focuses on both the use of diazotrophic bacteria in evaluating toxicity of a given crude oil and natural biodegradation half-life of the petroleum hydrocarbon in the given ecosystem, the ultimate goal being the development of a diagnostic tool for best decision making in the allocation of limited financial resources and best options for bioremediation strategies.
