This research shows that two types of fungi—Aspergillus flavus and Cunninghamella elegans—can effectively break down commonly prescribed medications found in wastewater through biofilm formation on foam carriers. The fungi degrade these drugs through enzymatic action rather than absorption, removing 85-99% of the pharmaceuticals within days. This discovery offers a promising, cost-effective biological treatment for cleaning wastewater from hospitals and pharmaceutical factories, potentially protecting aquatic environments from drug pollution.
