Summary

This research examines how certain fungi can clean up environmental pollutants in soil. White rot fungi, which normally break down dead wood in nature, can also break down harmful chemicals like pesticides using special enzymes. The study shows these fungi can work even in challenging environmental conditions where plants cannot grow. Impacts on everyday life: • Provides a natural way to clean up contaminated soil in agricultural and industrial areas • Offers an environmentally friendly alternative to chemical cleanup methods • Helps protect groundwater from pesticide contamination • Creates potential for recycling agricultural waste products like mushroom compost • Contributes to developing more sustainable farming practices by managing pesticide residues

Background

There is growing public concern over xenobiotic compounds being introduced into soil, which can have long-term impacts on decomposition processes and nutrient cycling. Many xenobiotic compounds have medium to long-term stability in soil, and their persistence significantly impacts soil ecosystems. While microbial metabolism is considered the most important mechanism for degrading these compounds, conditions like low moisture and nutrients can compromise this process.

Objective

This review aims to provide background information on bioremediation approaches and examine the roles of white rot fungi and their extracellular enzymes in degrading xenobiotic compounds. It explores how environmental factors like water potential, temperature, and pH affect bioremediation effectiveness, and discusses formulation and delivery methods for fungal bioremedial agents.

Results

White rot fungi demonstrate significant ability to degrade various xenobiotic compounds through enzymatic processes. Environmental factors strongly influence degradation effectiveness. Spent mushroom compost shows promise as a bioremediation adjuvant. The fungi can operate under water stress conditions where plants cannot grow. Different species show varying abilities to degrade single versus mixed pesticides.

Conclusion

Fungal bioremediation technology shows significant promise for treating contaminated soils. Future research should focus on mixed contaminant degradation under varying environmental conditions, including climate change impacts. The elucidation of fungal genomes, particularly P. chrysosporium’s cytochrome P450 monooxygenases, offers new opportunities for understanding and optimizing bioremediation processes.
