Using Microorganisms to Facilitate Phytoremediation in Mine Tailings with Multi Heavy Metals

During mining activities, a large amount of wastes in the form of mine tailings were discharged, leading to a global problem in soil and water contamination. Phytoremediation was considered to be a potential method for remediation of mine wastes as vegetation can promote remediation for sustainable development of mine waste sites. Recently, studies were conducted to utilize microorganisms such as plant growth-promoting bacteria, or filamentous fungi to facilitate phytoremediation by increasing the plant biomass production, bioavailability of heavy metals (HMs), enhancing the plant uptake of HMs or reduce toxicity of HMs to plants. Some species of microorganisms can be beneficial to phytoremediation in the mine tailings contaminated with HMs.
