10.22376/ijpbs.2019.10.1.p1-12 Volume 2 Issue 3 2011 (July - September) Remediation of Hg lessThan sup greaterThan ++ lessThan /sup greaterThan contaminated wastewater can be accomplished by Hg lessThan sup greaterThan ++ lessThan /sup greaterThan resistant lessThan i greaterThan Saccharomyces cerevisiae lessThan /i greaterThan A100. The physico-chemical mode of biosorption process is largely dependent on the charge bearing cell surface ligands. Optimum cell growth and multiplication provides the exposure of adequate amount of charged ligands on the cell surface that ultimately facilitate greater rate of biosorption of Hg lessThan sup greaterThan ++ lessThan /sup greaterThan . Hence, The growth promoting factors like vitamins , amino acids indirectly play a significant role in biosorption process. Thiamine-HCl (2.0µg/ml) and biotin (1.0µg/ml) increases the biosorption upto 95.67% and 96.78% respectively. L(-)Tryptophan (0.75mg/ml) promotes the biosorption upto 90.24%. Complex nutrients are the cheap sources of vitamins, amino acids, metals in trace amounts etc. Among 10 different tested complex nutrients, meat extract and soya been meal show some positive effect where as peptone and rice bran extract significantly declines the biosorption potential of the used biomass.
