ABSTRACT

 

The use of microorganisms for bioremediation of heavy metals has generated growing attention in the present era for environmental protection. The paper describes the use of Neurospora intermedia cultures for removal of copper from solutions and projects their use for bioremediation of copper contaminated soils and water. Neurospora intermedia cultures were isolated from soil and were adapted to grow on high concentrations of copper by gradual sub-culturing on increasing concentration of copper in the media. The extension growth and biomass of adapted and non-adapted strains were compared at different concentrations of copper to determine the potential of these cultures to grow in presence of copper. It was found that, at all concentrations of copper, adapted strains showed better growth than non-adapted strains. The non-adapted strains showed poor or negligible growth at concentrations like 400 and 500 ppm. The copper removal ability of non-adapted and adapted strains was compared quantitatively by iodometric determination of residual copper left in the media. Thus, it appears that, adapted strains can be used for bioremediation of copper from polluted soils or water.
