Kesan Kepekatan Mangan Terhadap Biojerapan Mangan oleh Pencilan Bacillus Cereus Tempatan (Effect of Initial Concentrations on Biosorption of Manganese by Locally Isolated Bacillus Cereus)
Journal Title: Jurnal Kejuruteraan - Year 2016, Vol 28, Issue 1
Abstract
Problem of manganese (Mn) pollutions that found in water is highly toxic to living thing, which can cause gastro intestinal accumulation, low heamoglobin levels in blood, neurotoxicity, nausea, water appears reddish brown and also can cause of clogged pipes. Biosorption of manganese is done using difference concentration of Mn concentration which is 25, 40 and 100 mg/L. The analysis of this study were optical density (OD), pH, manganese concentrations, biomass and colony forming unit (CFU). The result shown for OD, pH and biomass increased over time reflects the growth of bacteria. Concentration of Mn decreased from 25, 40 and 100 mg/L to 10.2, 18.6 and 52.2 mg/L with the percentage removal of 55, 53 and 50 % respectively after 24-hour incubation period. Meanwhile, the uptake of Mn by B.cereus decreased as increased the initial concentrations. Therefore, increasing the initial concentrations of Mn affected the biosorption of Mn by locally isolated B.cereus.
