摘要：
Mine tailings represent a serious environmental pollution problem and techniques such as phytoremediation using plant growth-promoting bacteria become an important solution due to their environmentally friendly nature. The study performed using Brassica juncea L. (Indian mustard) and plant growth-promoting bacteria such as Serratia K120, Enterobacter K125, Serratia MC107, Serratia MC119 and Enterobacter MC156 showed that plant roots colonization favored the transfer of metals to the plant, mainly Al and Pb from the 8 analyzed metals with bioaccumulation factors > 1 for Al, Pb, Cd and Fe obtained with Serratia K120, Enterobacter K125, Serratia MC107, Serratia MC119 and Enterobacter MC156. Based on these results, this system could be used in phytoextraction processes whereas Enterobacter MC156 reduced the bioaccumulation of metals, indicating the possible phytostabilization of metals present in mine tailings.
