There are several ways to remove and treat toxic heavy metals in the environment: chemical, physical and biological ways. The biological treatment utilizes the natural reactions of microorganisms living in the environments. These reactions include biosorption and bioaccumulation, oxidation and reduction, methylation and demethylation, metal - organic complexation and insoluble complex formation. The biological reactions provide a crucial key technology in the remediation of heavy metal-contaminated soils and waters. According to recent reports, various kinds of heavy metal species were removed by microorganisms and the new approaches and removal conditions to remediate the metals were also tried and reported elsewhere. This was mostly carried out by microorganisms such as fungi, bacteria and alga. In addition, a recent development of molecular biology shed light on the enhancing the microorganism's natural remediation capability as well as improving the current biological treatment.
