Degradation of High Concentrations of Anthracene Using White-Rot Wood-Inhabiting Fungi and Investigation of Enzyme Activities

mycolabadmin

Scientists in Iran discovered that certain wood-decay fungi, particularly Trametes versicolor mushrooms, can effectively break down anthracene, a toxic pollutant from oil and gas industries. These fungi produce special enzymes that degrade the harmful chemical into less toxic substances. In laboratory tests, these indigenous Iranian fungi successfully removed 20-64% of high-concentration anthracene over four weeks, showing promise for cleaning up contaminated sites.

Advances in the Degradation of Polycyclic Aromatic Hydrocarbons by Yeasts: A Review

mycolabadmin

This review explores how yeasts, tiny single-celled fungi, can clean up environments contaminated with polycyclic aromatic hydrocarbons (PAHs) – harmful chemicals produced by car emissions, factories, and burning. These yeasts use special enzymes to break down these toxic compounds into less harmful substances, making them a promising natural solution for environmental cleanup. Scientists are also improving these yeasts through genetic engineering to make them even more effective at removing pollution.

Extremely chaotolerant and kosmotolerant Aspergillus atacamensis – a metabolically versatile fungus suitable for recalcitrant biosolid treatment

mycolabadmin

Scientists discovered a special fungus called Aspergillus atacamensis that can survive in extremely salty environments, similar to salt lakes in the Atacama Desert. This fungus is remarkable because it can break down harmful pollutants and chemicals, including medications and oil-based compounds. Researchers tested its ability to clean contaminated wastewater and biosolids, finding it highly effective at removing various contaminants. This discovery opens new possibilities for using this hardy fungus to clean up environmental pollution in industries and wastewater treatment facilities.
