| Article Name : | | | BIOREMEDIATION OF HEAVY METAL FROM PAPER MILL AND USING POTENTIAL OF MERCURY RESISTANT BACTERIAL STRAIN | | Author Name : | | | S.R.PARANTHAMAN AND B.KARTHIKEYAN. | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | ROR-246 | | Article : | |  | Author Profile | | Abstract : | | | Use of microorganisms for removing mercury is an effective technology for the treatment of industrial wastewaters and can become an effective tool for the remediation of man-impacted ecosystems with this metal.Nonviable biomass of an estuarine Bacillus sp. was employed for adsorbing Hg ions from aqueous solutions at six different concentrations. Most of the mercury adsorption occurred during the first 24 -72 hrs. It was found that changes in pH have a significant effect on the metal adsorption capacity of the bacteria, with the optimal pH value between 6.0 and 9.0 at 300C The impact of concentration on biomass production was also evaluated using various concentration (0, 0.5, 1.0 1.5, 2.0 and 2.5%) in NB with 10ppm mercury as substrate were used. | | Keywords : | | - Heavy metal
