Bioremediation is an effective and environment-friendly treatment used to clean up hydrocarbon-contaminated soil. However, the effectiveness of this treatment is often limited by the low bioavailability of the target contaminants. Surfactants addition thus appears as a way to increase solubility of these hydrophobic molecules and consequently improve their bioavailability.

However, the effectiveness of this treatment is often limited by the low availability of targeted contaminants. Biosurfactants produced by some microorganisms can increase organic compound solubility and might then overcome this limitation.

- - Bioaugmentation with Pseudomonas putida enhanced the ability of sunflowers to extract copper (Cu) from vineyard soils, increasing Cu concentration in roots by 93% and in shoots by 17%, while also boosting sunflower biomass by 30% to 60%.
- - The study focused on the mechanisms behind copper transfer from soil to plants, highlighting the role of siderophores, particularly pyoverdine (Pvd), which formed a 1:1 complex with Cu, aiding its mobilization and availability for the sunflowers.
- - Interestingly, carbonated soils did not enhance the mobilization of trace elements as expected, suggesting that further optimization could involve strategies to enhance the dissociation of the Pvd-C
