Human activities such as industry and agriculture have resulted in the high contamination of soil and water with heavy metals. This type of contamination induces harmful effects on environmental and human health. In the last years, research on phytoremediation has highlighted the scientific and economic benefits of plants and their associated microorganisms used for the reclamation of polluted soil and water. Also, the potential of microorganisms to enhance phytoremediation processes and the exact mechanism by which bacteria could enhance heavy metal accumulation in plants has been received some attention. Despite the great interest in improving the efficiency of metal hyperaccumulating plants, their influence on microbial community’s remains poorly elucidated, constituting a less explored aspect in phytoremediation processes.
The aim of this study is to investigate the impact of the plant hyperaccumulator (Thlaspi spp.) on the diversity and structure of soil bacterial communities during phytoextraction processes. The present study aimed to assess the impact of the Thlaspy spp. on the bacterial communities along phytoremediation process in Cd and Pb-contaminated soil from Estarreja region.
Results will contribute to establish efficient strategies of risk assessment and phytorremediation in Estarreja.
