| Abstract | ||
| Nano-bioremediation approach involving the synergistic interaction between indigenous microorganisms and nanoparticles offers an affordable, environmentally, and beneficial solution for wastewater treatment. Herein, environmentally benign, Eichhornia crassipes-mediated green synthesized iron oxide nanoparticles (GS-IONPs) were prepared. The as-prepared GS-IONPs were properly characterized using different spectral analyses. Moreover, a bacterial microbiome was systematically isolated from a wastewater treatment unit located in the natural gas facility, Port Said, Egypt, and grown on a nutrient agar medium. The growth-enhancing effect of GSIONPs on the bacterial community at different interval periods was studied. Bioremediation activity of employed bacterial consortium towards crude oil was carried out. The outcome data experimentally symbolized that the bacterial consortium was remarkably stable under pH of 7.0 and temperature of 37.0°C (optimized conditions). Besides, the growth of bacterial consortium was directly proportional to the concentration of GS-IONPs up to the optimum dosage of 0.04 g. Compared to the control sample (non-treated GS-IONPs specimen), the removal % of COD, BOD, and TOC interestingly improved by 74.76, 77.17, and 85.44%, respectively (e.g., 0.04 g of GS-IONPs). Overall, the present study illustrates an ample perspective of nano-bioremediation feasibility as a futuristic rational platform for decontamination of crude oil wastewater using a hydrocarbon-degrading bacterial consortium. | ||
