Abstract:

The dissolution and complexation of heavy metals by resistant microorganisms can improve the bioavailability of heavy metals in soil, thus enhancing the absorption and enrichment of heavy metals by plants. In addition, plant hormones secreted by resistant microorganisms can promote plant growth, expand biomass, and further improve the efficiency of phytoremediation in heavy metal contaminated soil. Therefore, the mechanism and practical application of resistant microorganisms in strengthening phytoremediation in heavy metal contaminated soil were reviewed, and the shortcomings and future research directions were analyzed to provide a theoretical basis and a new way to develop and improve the phytoremediation measures of resistant microorganisms.

Key words: Resistant Microorganisms, Heavy Metal Contaminated Soils, Bioavailability, Plant Growth Promoting, Phytoremediation
