abstract

• Cadmium (Cd) is a heavy metal found in the environment because it is released from natural and anthropogenic sources. Cd is a persistent, nonbiodegradable pollutant with great toxicity for plants, animals, and microorganisms. Although Cd toxicity, some microorganisms can inhabit different environments contaminated with toxic levels of Cd2 because they have developed Cd tolerance and detoxification mechanisms. These mechanisms include the production of extracellular chelating compounds, the adsorption of Cd2 in the cellular surface, the transport of Cd2 from the cytoplasm using efflux pumps, and Cd intracellular complexation with glutathione, metallothionein, and phytochelatins. This chapter shows the state-of-the-art of Cd-tolerant microorganisms and describes the main mechanisms employed in Cd tolerance by bacteria and fungi.
