In this chapter, we provide several tools and protocols that should be followed to develop successful research on soil bioremediation. We propose step-by-step guidance towards the study of a contaminated site as a possible target for bioremediation. Some tips regarding the selection of the target site are provided. General protocols and international standards on sampling were taken into account, to maintain the integrity of the samples and their correct management for the following treatments at the laboratory. Microbial isolation and their abilities for bioremediation vary according to the nature of the sample and as a consequence different methodologies were proposed. Assays developed with cultivable microorganisms to select those able to act on the contaminant of interest were also described. When the selection was completed, the analysis to establish the mechanisms involved in the interactions with the contaminants were described. Finally, we focused on the use of molecular biology approaches, such as proteomics and genetics to evaluate how microorganisms reacted in the presence of the contaminant.This chapter includes specific highlights on the main issues to take into account when starting research aiming towards soil bioremediation, so we expect it will be useful for researchers working on this topic.
