Anti-cancer fungus found to naturally eat away plastic waste

by: Jonathan Benson

What if it was possible to eliminate much of the world's otherwise very-slowly-biodegrading plastic waste using a natural Amazonian fungus? Well, it just might be, thanks to research conducted by Jonathan Russell and colleagues from Yale University's Department of Molecular Biophysics and Biochemistry, who recently discovered that Pestalotiopsis microspora effectively eats away polyurethane (PUR) plastics, and is capable of using plastic as its sole food source in both aerobic and anaerobic environments.

Entitled Biodegradation of Polyester Polyurethane by Endophytic Fungi, the study aimed to find new potential plant sources of bioremediation, also known as the use of microorganisms to biodegrade and eliminate pollutants that otherwise persist in the environment. Several students attending Yale's annual Rainforest Expedition and Laboratory course collected various samples from the Yasuni National Forest in the Amazon basin, and took them home for testing.
