Economic and Regulatory Aspect of Fungal Bioremediation

Abstract

Fungal bioremediation is the process of detoxification and degradation of environmental pollutants through the metabolic capability of fungi. It involves heavy metals, hydrocarbons, and persistent organic compounds. Fungi possess diverse enzymatic systems like laccases, peroxidases, and hydrolases that convert contaminants into less toxic forms. It thus serves as an eco-friendly and cost-effective method to reduce pollution. Filamentous fungi are especially suited to wastewater treatment because they can convert organic material directly into proteins, carbohydrates, and valuable byproducts in accordance with circular economy principles. Lifecycle assessments are critical in determining the economic and environmental impacts of fungal-based remediation, mainly when fungi are grown on wastewater for food and feed purposes. Compliance with regulations is important in ensuring the safety and acceptability of products derived from fungi, especially regarding food and agricultural applications. The greatest challenge is still to public perception, and hence education and transparency will be critical to achieve more general acceptance. Market trends indicate massive growth in fungal bioremediation due to tighter environmental regulations, the social responsibility of companies, and increased demand for sustainable technologies. China, the United States, and Europe dominate patents and innovation in this area. Although fungal bioremediation still holds much promise, it still holds hurdles such as scale in operation, significant capital investment, the regulatory barrier, and the variability of environments. Innovations in omics technologies and hybrid remediation models are in process to overcome this limitation. Fungal bioremediation mitigates hazards caused by environment without producing unwanted economically non-viable by-products as it produces value adding byproducts of enzymes, biofertilizers and bio-energy for the mitigation of global environmental challenges.
