摘要

Wastewater treatment remains a global challenge, and not all conventional methods are successful from the perspective of sustainability and cost-effectiveness. Bioremediation, which leverages the metabolic activities of microorganisms, plants, and biological agents to degrade or neutralize pollutants, is increasingly recognized as a promising and sustainable remediation strategy. This review discusses the processes of bioremediation, including microbial degradation, bioaccumulation, and phytoremediation, and highlights their applications to various wastewater pollutants such as heavy metals, organic compounds, and nutrients. Special emphasis is placed on recent advancements such as genetically engineered microorganisms, nanotechnology-based enhancements, and integrated biological systems. By consolidating these developments, the review demonstrates the significance of bioremediation as a sustainable, cost-effective, and environmentally safe alternative to traditional wastewater treatment methods. It provides a comprehensive overview of recent advancements, technological innovations, and future opportunities that can assist researchers and practitioners in developing more efficient remediation systems. Finally, the review outlines emerging research directions needed to position bioremediation as a reliable and sustainable component of future wastewater treatment methods.
