Potential of Citrobacter freundii for bioaccumulation of heavy metal - copper

J Sharma, MH Fulekar*

The small scale industries located at Mira Road, Mumbai, are engaged in various processes/operations which generate the wastes. The waste generated are collected and disposed of at the dumping ground near the industrial estate. In the present study, the physico-chemical and microbial status of the contaminated sites has been carried out. The heavy metal with special reference to copper was exposed to microbial consortium at increasing concentrations viz 5, 25, 50, 75, 100 up to 800ppm to isolate potential microorganism for bioremediation. Citrobacter freundii has been identified by 16SrDNA technique as potential microorganism for bioaccumulation/bioremediation of copper. This organism can be used for remediation of copper from contaminated environment.
