Effect of Temperature and Salts on Phenol Bio-Availability in Polluted-Sandy- Soils: A Practical Biotechnological Approach before Microbial Bioremediation

Gularte HF, Diaz ME, Rendueles M, Gutierrez A, Jaili E, Diaz M

Despite the huge amount of accidental spills of phenols and other similar compounds, it is still unclear for real cases how to work and clean huge amounts of polluted sandy soil with high phenol concentration, especially with factors related to the adsorbed fraction and its bio-availability for a bio-treatment process. This new approach is about how by the control of clean operation conditions, like natural soil characteristics, pH, salts (type and concentration), solid-liquid relation, stirring speed and temperature, it is possible to decrease or increase the adsorbed fraction and bio-availability of phenol in ex-situ reactors. The results of this work allowed enhancing phenol bio-availability and reducing its absorption in studied polluted soils. In addition, this showed how soil complexity works and interacts with analytes in media and opens the door for a real world process to bio-remediate similar soils in all kinds of environmental conditions.
