In this study, the waste bacterial biomasses of Corynebacterium glutamicum and Escherichia coli were used as biosorbents for biosorption of Mo from the chemical wastewater generated in SK Chemical Co. Ltd. The raw C. glutamicum was treated with citric acid (CA) and polyethyleneimine (PEI) for enhancing the binding sites on the biomass surface. The batch biosorption experiments were carried out using the raw, CA-modified (CAB) and PEI-modified (PEIB) C. glutamicum, and raw E. coli. The biosorption did not happen when the biosorbents were brought into contact with the original wastewater. However, after adjusting the pH at 4 using 2N H2SO4, the uptakes of Mo were enhanced as 45.59, 9.41, 47.18 and 44.21 mg/g for raw C. glutamicum, CAB, PEIB, raw E. coli, respectively. In addition to the pH effect, other factors affecting biosorption performance like temperature and contact time were also studied.
