Abstract

Phytoextraction actuated by hyperaccumulating or non-hyperaccumulating species could be improved by using a plant-microbe system thus contributing to novel promising methods for the cleaning-up of metal contaminated soils. Rhizobacteria of the genus Azospirillum have been extensively used for crop phytostimulation thanks to the positive interaction between bacteria and plants at root level. The implementation of Pb phytoextraction in contaminated industrial soils by applying the A. brasilense Sp245 to plants of indigenous species belonging to Mediterranean forestry was the aim of this work. Phytoextraction ability was evaluated in Myrtus communis and Laurus nobilis on the basis of the Pb content (Emission Spectrophotometer Atomic Plasma, ICP-AES), the growing speed and the vegetative habitus. Greenhouse trials were performed for 2 and 9 months, and plants were grown in pot in the presence of two level of Pb (312 and 4345 ppm).
