Scientists have created a mutant enzyme that breaks down plastic drinks bottles – by accident. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles.
The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug.
The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. “What actually turned out was we improved the enzyme, which […]
Exciting…make sure it does not destroy the cutin protection on plants? Uh oh
If this gets out into the wild, and it probably will, it could eat all the plastic we don’t want to recycle yet. Look at your computer- a lot of plastic.
If this enzyme eats plastic what does it excrete?
