ABSTRACT

Heavy metal contamination causes serious threat to the ecosystem. Microbe metal interaction has been most sought after topic in terms of the usage of microbes in removing heavy metals from the surrounding environment along with the bioremediation. It is the most efficient and least costly method for treating heavy metal contaminated areas. Varied number of bacteria, fungi, algae and yeasts had been reported for removing heavy metals effectively. Industrial waste, wastewater, soils, plant roots and compost have been found to be good sources of heavy metal resistant microbes. Biosorption technology applies to the inanimate biosorbents as well as to living and non-living microorganisms. Therefore, this review paper highlights the microbiological aspect of heavy metal removal in the wastewater, industrial effluents, and water from other contaminated regions. The application of microbial study in the aspects of heavy metal removal and purification of water with the adsorption technology has been focused. Thus, proving microbioremediation to be an effective field of research oriented towards heavy metal removal by microbes in the most effective, safe and economical way.

Keywords: Bioremediation; biosorption; biosorbents; microbioremediation.
