Bio-removal of Nickel ions by Sporosarcina pasteurii and Bacillus megaterium, A Comparative Study

The aim of this work was to study the potential of Sporosarcina pasteurii 586S and Bacillus megaterium 1295S isolated from sewage treatment plants (STPs) in removing of nickel ions from the aqueous solution. The bacterial cells were used as living and dead cell biomass. The efficiency of bio-removal...

Summary:The aim of this work was to study the potential of Sporosarcina pasteurii 586S and Bacillus megaterium 1295S isolated from sewage treatment plants (STPs) in removing of nickel ions from the aqueous solution. The bacterial cells were used as living and dead cell biomass. The efficiency of bio-removal process was investigated as a response for nickel and biomass concentrations, time, pH and temperature. The bio-removal capacity (Qmax) of both strains were compared. The highest bio-removal percentage was recorded by dead cells in comparison to living cells. Dead cell biomass of B. megaterium 1295S exhibited higher efficiency for bio-removing of Ni2+ than S. pasteurii 586S at196.4 and 200.2 mg Ni2+ g-1, respectively. It can be concluded that both bacterial strains have high potential to be applied in the biotechnology for removing of Ni2+ ions, however, dead cells of B. megaterium 1295S is the most potent.
