Optimisation de la phytoextraction : caractérisation et sélection de bactéries PGPB associées à une plante hyperaccumulatrice de Zn et Cd : Arabidopsis halleri

Abstract : Phytotechnologies are microbial-assisted techniques that use living plants for the treatment of contaminated sites. Among these, phytoextraction based on hyperaccumulator plants such as Arabidopsis halleri, may be an option to remove trace elements in soil. One method to optimize Arabidopsis halleri phytoextraction is the inoculation of plant roots by plant growth promoting bacteria (PGPB). In this study, we proposed a protocol for sampling bacteria in three different soil fractions neared root system of Arabidopsis halleri: global, rhizospheric and rhizoplan. The cultivable bacteria were isolated for a Zn and Cd contaminated industrial soil (Auby, France) and were isolated and characterized for their PGPB traits : 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity, siderophores and Indol-Acetic-Acid (IAA) productions). Bacteria answering positively to the three PGPB tests have been preferentially selected to be inoculated to Arabidopsis halleri root system. Bacteria effects on plant biomass and/or accumulating yield will be presented.
