Bioremediation of Metals: Microbial Processes and Techniques

Bioremediation has developed from the laboratory to a fully commercialised technology over the last 30 years in many industrialised countries. However, the rate and the extent of development has varied from country to country. A successful bioremediation scheme relies on the management of soil microbial populations capable of catabolising the contaminants. The role of soil microbiota in the biochemical conversion of organic and inorganic contaminants has been realised, priority research needs have been identified and effort has been made to understand the ecological, biochemical and genetic basis of microbial contaminant degradation, with a view to enhancing microbial capabilities and thus designing more effective bioremediation processes.
