DOIAbstract
Heavy metals concentrations in the environment increases alarmingly. Heavy metals profoundly affect biological systems either positively because they are essential in low concentrations or negatively because they are toxic. Bioremediation using microorganisms is a potential strategy for the decontamination of natural environments modified mainly by anthropogenic activities however the application of free microorganisms? presents many limitations. Immobilized cells have been extensively used as an important tool in some biotechnological processes because the immobilization increases cellular stability and survival. The use of immobilized microbial cells, as well as their metabolites capable of modifying toxic substances in natural environmen...
