| Abstract | ||
| The study aimed to use of baker’s yeast Saccharomyces cerevisiae in Bioremediation of some heavy metals. Several isolates were obtained from different sources. These isolates were subjected to serial diagnostic tests to ensure its belongings to S. cerevisiae. The ability of these isolations to remove of metal elements under constant conditions including incubation period (24 hours), pH ( 6 ), temperature 25C° and stirring speed (150 rpm / min) with inoculation size 1 × 106 cell / ml in a solution containing the metals in a concentration of 1 mg/ L as individual or as a collection were investigated. The results have been shown that the isolate which designated as Sc6 has the best ability to remove the metals over the all others. Chrome, Lead, iron and copper removing efficiency as individual by this isolate were 47.35%, 70.87%, 95.15% and 50.28%, respectively with a rate of 43.63%. While the rate of removal efficiency of lead, iron and copper as a group was 81.18%, but the rate of removal efficiency of chrome, nickel, cobalt and cadmium as a group was only 19.00 %. | ||
