Biosorption of Cr (VI) using different types of husks (Oryza sativa, Pennisetum typhoides and Vigna mungo)

Abstract :

The level of heavy metals is constantly increasing in drinking water, air and soil. Three heavy metals such as copper, chromium and mercury were used in the present study and the heavy metal biosorption was analyzed using free and immobilized cells of Bacillus subtilis and Pseudomonas aeruginosa, isolated from industrial waste water. The results of the present study suggest that the biosorption of heavy metal could be achieved by using Bacillus subtilis and Pseudomonas aeruginosa and they could be successfully used for the treatment of waste water.
