Removal of heavy metals from waste water using different biosorbents
The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...
متن کاملIsolation and molecular characterization of bacteria to heavy metals isolated from soil samples in Bokaro Coal Mines, India
In recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. The presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. The coal mine area in Bokaro is one of the “Toxic Hotspot” in India. Bacteria have evolved uptake and efflux mec...

15 صفحه اولTolerance of Heavy Metals by Gram Positive Soil Bacteria
With the intention of screening for heavy metal tolerance, a number of bacteria were isolated and characterized from a pristine soil. Two Gram positive isolates were identified as Paenibacillus sp. and Bacillus thuringeinsis. Tolerance of Cd, Cu and Zn by these bacteria was studied and found that both bacteria were highly sensitive to Cu compared to other two metals. Both bacteria showed the sa...
