ABSTRACT

 

The use of microorganisms for removing heavy metals from contaminated sites is an inexpensive and environment friendly strategy. The wild strains of microorganisms can rarely tolerate high concentrations of heavy metals which may be present in polluted environmental sites, so their use in bioremediation is limited. Hence, improved strains are required which can be used for removal of heavy metals from polluted sites in nature and industries. In the present study, Neurospora culture was isolated from soil and its copper removal efficiency was improved by mutagenesis. For mutagenesis, ethyl methane sulphonate (EMS) was used. The results show that the mutagenized culture could remove about 90.0% copper from the aqueous solution.
