| Abstract | Microorganisms are known to remove heavy metal ions from water and their utilization as biosorbents for heavy metal removal, offers a potential alternative to the existent methods for the detoxifi- cation and recovery of toxic/precious metals present in industrial wastewater. Many yeasts, fungi, algae, bacteria and some aquatic plants have the capacity to concentrate metals from aqueous diluted solutions, and to accumulate them inside the cell structure. To date, the most successful biotechnological processes utilize biosorption and bioprecipitation, but other processes such as binding by specific macromolecules may have future potential. Technologies using these processes are currently used to control pollution from diverse sources. In this article, th e term biosorption is used to encompass uptake by whole biomass (living or dead) via physico-chemical mechanisms such as adsorption or ion exchange. Where living biomass is used, metabolic uptake mechanisms may also contribute to the process. Mention is made about systems that employ a mixture of microorganisms as well as higher plants. |
