Many people are constantly working towards reducing the use of plastics in everyday life. And the amazing news is that scientists seem to have come up with a solution that grows on its own. A study from the University of Maine, USA, highlights a mushroom-based coating that could one day replace plastic wraps and synthetic cup linings. Read to know more details.
Mushroom To Replace Plastic Wraps Soon?
The scientists wanted to see if an edible mushroom and processed wood fibres could work together to form a protective coating. They aimed to create something safe for food, simple to produce, and powerful enough to block water, oil and grease. For effective results, they tested the coating on common materials used in everyday life, reported Interesting Engineering.
Their research led them to the turkey tail mushroom (Trametes versicolor). This mushroom grows on wood and develops a thick layer of mycelium, which is made of thin strands. These strands naturally act like a shield and help stop water from soaking in.
To make the coating stronger, the team combined the mycelium with cellulose nanofibrils, which are tiny fibres used in making paper. These fibres help create tough films that block oxygen, liquids and oil. When mixed with the mycelium, they produced a smooth, tight layer that stuck well to different surfaces.

How This Coating Was Made
To make the coating, the scientists decided to grow the fungus in a liquid that also had cellulose nanofibrils. They applied thin layers of this mixture on materials like paper, denim, polyester felt and birch wood. These samples were kept warm so the fungus could grow properly on the surfaces. The results were seen from the third day when the material developed a strong water-resistant layer.
On the fourth day coating grew a bit thicker and showed light-coloured patches where the fungus expanded. The researchers then dried the samples in an oven to stop the growth and harden the coating. The final layer was about as thick as a coat of paint. According to Fossbytes, tests showed it could block various liquids like castor oil, toluene, and n-heptane. This demonstrated that it provides protection well beyond just water.
This study was a hit and concluded that mushroom-made coating can be the right replacement for plastic wraps.
