removing heavy metals - Opis:
- The research on the effectiveness of removing heavy metals from water solutions by bacteria was carried out at the laboratory of the Institute of Environmental Engineering of the University of Zielona Góra in 2007-2008. The research covered bacterial strains isolated from sludge, soil and water. The tests concerned the effect of 3 heavy metals: Pb (0,1%), Cu (0,1%) and Zn (0,1%). The results prove that due to the presence of heavy metals, the size of colonies was much lowered in comparison with the control pan. Some of the strains, reader doesnt know numbers in the 0,1% concentration of Cu and Zn in the culture scale. It turns out that this concentration was completely hazardous with respect to the growth of those bacterial strains. Considering all the heavy metals under analysis, it was found that Cu had the most hazardous effect on the growth of 4 bacterial strains, then Zn and Pb. Under the influence of 4 bacterial strains, the content of the metals that after 7-day long incubation remained is different depending on metal and bacterial strain. Removing Heavy Metals by bacteria from Water solutions heavy metals by bacteria from water solutions: Pb (34,38%), then Cu (29,69%) and Zn (21,88%). The content of the heavy metals removing by 4 strains was from 65,62% to 78,12%. The biggest amount removing was for Zn (78,12%) and the smallest for Zn (65,62%).
