Petroleum hydrocarbon contamination is a significant environmental issue that requires innovative and sustainable remediation strategies. Fungal bioremediation is a promising approach that utilizes the metabolic capabilities of diverse fungal species to efficiently degrade hydrocarbons. This eco-friendly approach is based on the selection of hydrocarbon-degrading fungi, which are then isolated and screened for their specific hydrocarbon-degrading capabilities. Genetic engineering techniques are used to introduce genes encoding enzymes crucial for breaking down complex hydrocarbon structures, enhancing their remediation potential. Biostimulation and bioaugmentation strategies optimize environmental conditions and nutrients to promote fungal growth and metabolic activity. Bioremediation enhances hydrophobic hydrocarbon bioavailability, while mycorrhizal fungi improve remediation outcomes. Ex situ and in situ applications target contamination at the source, with real-time monitoring techniques guiding adaptive optimization strategies. Hybrid systems, combining fungal bioremediation with phytoremediation, capitalize on the strengths of both approaches. The diverse array of methods presented in this chapter reflects the dynamic and versatile nature of fungal bioremediation, offering a holistic perspective on potential applications and advancements in this field. Further research is required to optimize bioremediation strategies and develop novel solutions for challenging contamination scenarios.
