Fenton-fungal reactor for biodegradation of persistent organic pollutants

This technology is a fungal-based biodegradation system that utilizes white rot fungi and Fenton reactants to degrade persistent organic pollutants efficiently.

Unmet Need: Biodegradation of persistent pollutants

Persistent organic pollutants such as lignins, perfluorochemicals, and certain plastics pose significant environmental challenges due to their resistance to conventional degradation methods. Current biodegradation technologies are often costly, resource-intensive, and limited in their effectiveness, especially for complex compounds. As these persistent compounds may have detrimental effects on both human and environmental health, there is an urgent need to develop effective and sustainable waste management methods targeting this group of contaminants.

The Technology: Fungal-fenton reactors for organic pollutant breakdown

This system combines a culture of white rot fungi with Fenton reactants—hydrogen peroxide and a concentration of ferrous ions— to create a synergistic degradation process for recalcitrant organic compounds. The white rot fungi degrade lignin-like compounds, while the Fenton reactants facilitate the breakdown of more resistant chemicals. This system uses lower hydrogen peroxide concentrations than typical Fenton reactions, reducing costs. Additionally, the fungi recycle ferrous ions, which sustains the reaction cycle, and suppress microbial competitors, which enhances overall efficiency.
