Much of the attention was given to microbial hydrocarbonbiodegradation, while limited work is present regarding the capacity of fungal biosurfactants for enhancingthe remediation process. This research work identified the potential of biosurfactant production and hydrocarbon degradation of selected fungal strains belonging to Aspergillus, Penicillium, and Candida genera incontrast to a hydrocarbon-degrading and biosurfactant non-producing fungal strain. The highest biodegradation was noted for Aspergillus niger FA5 (90.7%), followed by Penicillium chrysogenum FP4 and Aspergillusterreus FP6 (87.4 and 85.0%, respectively), and lastly, Candida sp. FG2 (80.1%). Biosurfactant-producinghydrocarbon degrading fungal strains A. niger FA5, P. chrysogenum FP4, A. terreus FP6, and Candida sp. FG2degraded hydrocarbons 1.32-, 1.27-, 1.24-, and 1.18-fold higher than non-producing A. flavus FP10 (68.6%).When the data were analyzed for correlation, hydrocarbon degradation was found negatively corelated to surface tension (r = –0.747, p = 0.005), while positively correlated with emulsification index (r = 0.964, p <0.001), and cell hydrophobicity (r = 0.835, p < 0.001). The results indicate that fungi capable of attachinghydrocarbons at high concentration to the cell surface and effectively reducing surface tension were able toexhibit significant improvements in the rate of hydrocarbon degradation. Hence, it is concluded that if a fungus can produce biosurfactant that can improve hydrocarbon emulsification and reduce surface tension, thehydrocarbon breakdown can be accelerated from 12 to 22% compared to non-producers PB Springer SN 0003-6838 YR 2023 FD 2023-06 LK https://hdl.handle.net/10259/11840 UL https://hdl.handle.net/10259/11840 LA eng NO The authors are highly thankful for the research faculties provided at Quaid-i-Azam University, Islamabad, Pakistan.
