As a Microbiologist working on a bioremediation project, you are torn between 2 choices for remediation of soil contaminated with jet fuel. Your first option is to fertilize the soil with nitrogen and phosphorus for possible promotion of growth hydrocarbon-degrading microorganisms. For your second option, there is a possibility of using a new commercial microbial inoculum containing hydrocarbon-degrading microorganisms, nutrients and surfactants. What information will you need to decide on the best approach?
