Abstract

In recent years, due to the geological and anthropogenic activities, metal pollution in soil has been increased drastically. Utilization of microorganisms to remediate the metal-contaminated soil is known as bioremediation. Bioremediation is an important area of research that offers economically effective clean-up technique than the conventional methods. Microorganisms use different mechanisms such as biosorption, bioaccumulation, chelating agents, bioleaching, biomineralization and enzyme-catalysed transformation to convert toxic form of metals to less toxic form. In addition, plants also offer various methods like absorption and accumulation of metals in plant cells and formation of metal-bound compounds. Integrated use of microorganism and plant in bioremediation may ensure an effective clean-up of heavy metals in polluted soils. This chapter summarizes the microbial- and plant-microbe-mediated methods for the clean-up of heavy metal-contaminated soil.
