Researchers accidentally engineer plastic-eating enzyme
Researchers in the US and Britain have accidentally engineered an enzyme which eats plastic and may eventually help solve the growing problem of plastic pollution, a study said.
Scientists at the University of Portsmouth and the US Energy Department's National Renewable Energy Laboratory decided to focus on a naturally occurring bacterium discovered in Japan a few years ago.
The researchers' goal was to understand how one of its enzymes - called PETase - worked, by figuring out its structure.
"But they ended up going a step further and accidentally engineered an enzyme which was even better at breaking down PET plastics," said the report in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal.
