Lead bioremediation with Saccharomyces bloulardii

Abstract

The main routes of exposure to lead are eating food, adsorbing the skin, drinking water, and breathing the air. This exposure causes many of human health problem. Bioremediation is an ecofriendly, effective and has greater public acceptance. 'The bioremediation process was carried out using Saccharomyces bloulardii' yeast and lead at concentration of (0.1,0.2,0.3 mg/ml) under PH=7 condition at 35°C and for a period (24,48,72 hours), and anatomic absorption spectroscopy was used to analyze the concentration of lead after the completion of the treatment process. The results indicate that the highest removal of lead was % at 0.1 mg/ml and lowest removal by 0.2 mg/ml, and the best elimination period was at 72 hours.
