The role of plant-associated bacteria in the mobilization and phytoextraction of trace elements in contaminated soils
Phytoextraction makes use of trace element-accumulating plants that concentrate the pollutants in their tissues. Pollutants can be then removed by harvesting plants. The success of phytoextraction depends on trace element availability to the roots and the ability of the plant to intercept, take up,...
