EFFECTS AND MECHANISMS OF MICROBIAL REMEDIATION OF HEAVY METALS IN SOIL: A CRITICAL REVIEW
Jin, Y., Y. Luan, Y. Ning, and L. Wang.
Applied Sciences 8(8):1336(2018)
Following a review of the origins and toxic effects of heavy metal pollution in soil, this paper describes the heavy metal accumulation mechanisms of microbes and compares their different bioconcentration abilities. Biosorption, which depends on the special structure of the cell wall, was found to be the primary mechanism. Furthermore, Escherichia coli were found to adsorb more heavy metals than other species. Factors influencing microbial treatment of wastewater and soil containing heavy metals included temperature, pH, and different substrates. In conclusion, problems in the application of microbial treatment of heavy metal contamination were considered with a discussion of possible directions for future research. https://www.mdpi.com/2076-3417/8/8/1336/pdf
