Abstract: Biosorption of Cu(II) ion from aqueous solution was studied using Bacillus cereus M1 16 immobilized in calcium alginate and agar agar gel in batch mode. Uptake of metal was very fast initially and equilibrium was attained within 240 min. Sorption data conformed well to both Freundlich and Langmuir isotherm model. Highest Cu(II) uptake (87.32%) by selected biomass (3.09 g/l, dry wt) immobilized in 3% calcium alginate occurred at 30°C, 120 rpm when initial copper concentration was 50 mg/l.
