Remediation of heavy metal pollution in soil by microbial immobilization with carbon microspheres

Abstract

Cultivate resistant strains in soil contaminated with heavy metals, improve the survival rate of strains in microbial remediation, and use the interaction between resistant strains and contaminated soil to achieve the purpose of remediation of heavy metal pollution in soil. Using carbon microspheres as the carrier of bacterial strains, the bacterial strains were fixed reasonably and the survival rate was high, which was conducive to the formation of stable bacterial colonies and the reduction of heavy metal pollution.
