Potential biodegradation of polycyclic aromatic hydrocarbons (PAHs) and petroleum hydrocarbons by indigenous fungi recovered from crude oil-contaminated soil in Iran

mycolabadmin

Scientists isolated fungi from oil-contaminated soil in Iran to find species that can break down petroleum pollutants. Two fungi species, Alternaria tenuissima and Epicoccum nigrum, showed exceptional ability to degrade harmful oil compounds called PAHs. When applied to contaminated soil in the laboratory, these fungi successfully eliminated over 70% of the long-chain hydrocarbons. This research offers a natural and cost-effective way to clean up oil-spilled soil without using harsh chemicals.

Degradation of Extra-Heavy Crude Oil by Fungi Isolated from Hydrothermal Vents Fields in the Gulf of California

Scientists discovered that certain fungi living in deep-sea hydrothermal vents can break down extra-heavy crude oil, a thick and difficult-to-treat form of petroleum. Among eight fungal species tested, Aspergillus sydowii was the most effective, degrading 40% of the crude oil in laboratory conditions. This research suggests these hardy deep-sea fungi could be used as a natural solution to clean up oil spills in extreme marine environments where traditional cleaning methods don’t work well.
