Abstract

Petroleum hydrocarbons (PHCs) are important energy sources widely used in industries and daily activities. However, accidental spills from petroleum industries and other huma n activities have resulted in severe soil contamination, making PHC pollution a major env ironmental concen worldwide. The accumulation of these pollutants in soil threatens en vironmental safety and public health, thereby increasing the need for effective remediati on strategies. Among the available methods, bioremediation has emerged as an environ mentally friendly and sustainable approach for restoring PHC-contaminated soils. This s tudy aimed to evaluate the efficiency of fungal isolates in the bioremediation of PHC-co ntaminated soils. Fungi were isolated from PHC-contaminated soils using Potato Dextro se agar. The PHC-degrading efficiency of single fungal isolates was compared with fung al consortium by screening for their hydrocarbon degrading ability using lacto phenol blu e and Microscope for identification method. Findings revealed that several microbial spe cies have been successfully applied in the bioremediation of PHCs, highlighting the impo rtance of diverse microbial communities in hy drocarbon degradation. Among the fungal isolates studied, Aspergillus spp., Penicillium spp., and Trichoderma spp. Were identified as the most effective organisms for degrading PHC-contaminated soils.The study is sign ificant because it provides a comprehensive understanding of the mechanisms involved in PHC degradation and highlights the potential of fungal bioremediation as a sustainab le and cost-effective solution to environmental pollution. It also emphasizes the need for further research, complete degradation of contaminants, and flexible regulations guiding the safe use of genetically engineered microbes to improve the future application of bior emediation technologies.
