Patented process to boost phytoremediation

Phytoremediation is a strategy that aims at using certain plants capacities to absorb, to stock and/or to damage chemicals and organics contaminants from soils and water polluted.

The goal of the innovation is to increase plants perfomances through a simple natural technique allowing to circle the use of a genetical modified organism strategy. Studies have been carried out on Arabidopsis thaliana, a model for genetics and molecular biology on plants.

The invention is based on the addition of a natural molecule (sugar as glucose or saccharose) into the midium which enables to increase the plant tolerance (with a factor 500) and its ability to absorb towards some contaminants. This disclosure is based on a metabolic and genetic mecanism of activation through signalisation ways preserved by the majority of superior plants. Consequently, the process can be extended to other plants and other contaminants.
