Microbial bioremediation as a tool for the removal of heavy metals

[摘要] BackgroundThe demand for designing a new technology that can emphasize the complete removal of heavy metals increased as a result of the industrial revolution. Bioremediation was found to have a potent impact on the degradation of organic and inorganic environmental pollutants.Main bodyBioremediation is a multidisciplinary technology that possesses safe, efficient, and low-cost characteristics. Also, one of the important features of bioremediation technology is the in-situ treatment which reduces the possibility of transmitting the contaminants to another site. The application of genetic engineering, to engineer a microorganism to acquire the ability to remove different types of heavy metals at a time or to generate a transgenic plant, is considered one of the new promising bioremediation approaches.Short conclusionRemoval of heavy metal pollution still represents a big challenge for ecologists that’s why this review shed some light on bioremediation technology; its importance, mechanism of action, and prospects.
