Bioremediation and Monitoring of Aromatic-polluted Habitats

Bioremediation may restore contaminated soils through the broad biodegradative capabilities evolved by microorganisms towards undesirable organic compounds. Understanding bioremediation and its effectiveness is rapidly advancing, bringing available molecular approaches for examining the presence and expression of the key genes involved in microbial processes. A global analysis of which genes are being expressed under various conditions in contaminated soils will reveal the metabolic status of microorganisms and indicate environmental modifications accelerating bioremediation.
