Abstract

In recent times, the treatment of harmful algal blooms (HABs) became an important environmental issue to preserve and remediate water resources globally. In the present study, the adsorptive removal of harmful algal species Microcystis aeruginosa directly from an aqueous medium was attempted. Waste biomass (Escherichia coli) was immobilized using polysulfone and coated using the cationic polymer polyethylenimine (PEI) to generate PEI-coated polysulfone-biomass composite fiber (PEI-PSBF). The density of M. aeruginosa in an aqueous medium (BG11) was significantly decreased by treatment with PEI-PSBF. additionally, analysis using FE-SEM, confirmed that the removal of M. aeruginosa algal cells by PEI-PSBF was caused by the adsorption mechanism. According to the profiles of phosphorus for the algal cell growth in M. aeruginosa cultivating samples, we found that the adsorbed M. aeruginosa onto the PEI-PSBF lost their biological activity compared to the non-treated M. aeruginosa cells.
