Role of Fungi in Bioremediation of Paper Effluent

The paper industry is one of the major water-intensive industries and generates considerable quantities of wastewater during its manufacturing processes. Paper effluent may contain dyes, chemicals, salts, heavy metals and organic matter, which can adversely affect aquatic ecosystems and human health when discharged without adequate treatment. Conventional physical and chemical treatment methods may be associated with high costs, incomplete removal of pollutants and secondary pollution. Bioremediation using microorganisms provides an environmentally friendly approach for reducing pollutants present in industrial effluents. Marine fungi are increasingly recognized as promising bioremediation agents because they possess diverse enzymatic systems capable of transforming complex organic pollutants. Enzymes such as laccase, lignin peroxidase, manganese peroxidase and other oxido reductases can degrade or modify recalcitrant compounds present in paper and pulp wastewater. Marine fungi may also tolerate variations in salinity, pH and other environmental conditions, making them suitable candidates for the treatment of industrial effluents. Their ability to utilize organic pollutants as carbon or energy sources can contribute to the reduction of colour, chemical oxygen demand and other contaminants in wastewater. Therefore, the isolation and screening of indigenous marine fungi from coastal environments may provide potential strains for the biological treatment of paper industry effluent. Studying their decolourization and pollutant-removal capabilities can help identify efficient fungal strains for future bioremediation applications. The use of marine fungal microorganisms offers a sustainable and eco-friendly alternative to conventional treatment methods and may contribute to the development of cost-effective wastewater management strategies for the paper industry.
