Abstract A large number of industries are releasing their effluents directly into the environment containing heavy metals which are present in the form of their sulphates, acetates and other such salts posing a grave threat to the environment. With this comes the necessity for their removal from the environment. Although several conventional techniques are in practice that have gone a long way in cleaning up the metal contamination, yet the process and chemicals involved may leave back traces of new contamination. Several studies have revealed that certain microorganisms like the pseudomonas species can resist the toxicity of heavy metals even at high concentrations through the acquisition of specific resistance systems such as efflux and uptake mechanisms, extracellular precipitation etc. However, this metal absorbing ability is a direct response to the metal species concerned, and consequently, a particular organism may directly and/or indirectly rely on several survival strategies. As a result, microorganisms are viewed as a tool for the treatment of wastewater in biological processes, which have demonstrated their advantages over physicochemical processes.
