Fungal bioremediation is emerging as a powerful technique for wastewater treatment, utilizing the metabolic versatility of fungi to degrade a wide range of pollutants. Among the most effective are white-rot fungi (WRF) e.g. Phanerochaete chrysosporium, Trametes versicolor, and Pleurotus ostreatus, produces key enzymes like lignin peroxidase (LiP), manganese peroxidase (MnP), and laccase. These enzymes break down persistent organic pollutants, including polyaromatic hydrocarbons (PAHs), dyes, and pesticides. Other fungi like Aspergillus spp., Irpex lacteus, Penicillium spp., and Fusarium spp. contribute through their bioaccumulation of heavy metals and ability to degrade complex organic compounds. The mechanisms involved enzymatic degradation and bioaccumulation, making fungi particularly effective in wastewater treatment systems. Its ability to handle pollutants that resist conventional treatment, lower energy requirements, and compatibility with microbial systems for enhanced efficiency, making fungal bioremediation advantageous over conventional treatment. Challenges remain, particularly in scaling up these processes for industrial use. Further research is required to optimize fungal growth conditions and enzyme production for more effective wastewater treatment applications.
