Scientists have identified a soil fungus, which uses enzymes to rapidly break down plastic materials, an advance that could help deal with waste problem that threatens our environment.
Why is there a need for this?
Humans are producing ever greater amounts of plastic, much of which ends up as garbage. Since plastic does not break down in the same way as other organic materials, it can persist in the environment over long periods of time.
Now, researchers from the Chinese Academy of Sciences have found an unexpected solution to the growing plastic problem in the form of a soil fungus.
What about other methods to deal with plastics?
Attempts to deal with plastic waste through burying, recycling, incineration or other methods are variously unsustainable, costly and can result in toxic by-products, which are hazardous to human health.
About the new research
The researchers took samples of soil and various pieces of rubbish in hopes of finding an organism that could feed on plastic waste in the same way that other fungi feed on dead plant or animal material
Aspergillus tubingensis is a fungus, which ordinarily lives in the soil. In laboratory trials, the researchers found that it also grows on the surface of plastics.
It secretes enzymes onto the surface of the plastic, and these break the chemical bonds between the plastic molecules, or polymers.
