Bioremedial potential of microbial mechanisms of metal mobilization and immobilization.
نویسنده
چکیده
Microorganisms play important roles in the environmental fate of toxic metals and radionuclides with a multiplicity of mechanisms effecting transformations between soluble and insoluble forms. These mechanisms are integral components of natural biogeochemical cycles and are of potential for both in situ and ex situ bioremedial treatment processes for solid and liquid wastes.

Metal and radionuclide bioremediation: issues, considerations and potentials.
Recent demonstrations of the removal and immobilization of inorganic contaminants by microbial transformations, sorption and mineralization show the potential of both natural and engineered microbes as bioremedial tools. Demonstrations of microbe-mediated mineral formation in biofilms implicate this mode of microbial life in geological evolution and remediation of inorganic contaminants.
متن کاملMicrobial influence on metal mobility and application for bioremediation
Microorganisms are intimately involved in metal biogeochemistry with a variety of processes determining mobility, and therefore, bioavailability. The balance between mobilization and immobilization varies depending on the organisms involved, their environment and physicochemical conditions. Metal mobilization can arise from a variety of leaching mechanisms, complexation by metabolites and sider...
متن کاملA delve into the exploration of potential bacterial extremophiles used for metal recovery
A multitude of microbes are involved in the solubilisation of minerals and metals as this approach offers numerous advantages over traditional methods. This strategy is preferred as it is eco-friendly and economical, thus overcoming the drawbacks of the traditional approach of pyrometallurgy. Many different types of bacteria are employed in the process of Bioleaching, which are collectively gro...

متن کاملLead Transformation to Pyromorphite by Fungi
Lead (Pb) is a serious environmental pollutant in all its chemical forms [1]. Attempts have been made to immobilize lead in soil as the mineral pyromorphite using phosphate amendments (e.g., rock phosphate, phosphoric acid, and apatite [2-5]), although our work has demonstrated that soil fungi are able to transform pyromorphite into lead oxalate [6, 7]. Lead metal, an important structural and i...
