Researchers think the enzyme evolved in a Japanese waste recycling center.
The global team, led by Professor John McGeehan of the University of Portsmouth, UK, tested the evolutionary process of the enzyme, inadvertently discovering that they had improved the capabilities of the enzyme in breaking down PET bottles. "Although the improvement is modest, this unanticipated discovery suggests there is room to further improve these enzymes, moving us closer to a recycling solution for the ever-growing mountain of discarded plastics".
PETase was also tested on PEF plastic, a proposed plant-based alternative to PET that is similarly slow to degrade in nature.
They said that they are still working on improving the enzyme further to see if they can make it capable of breaking down PET plastics on an industrial scale. The newly discovered enzyme promises to recycle plastic bottles back into new clear plastic bottles, which would require much less virgin plastic. So, the researchers improved the structure of bacteria by adding amino acids. "This shows that by using PETase, PEF is even more biodegradable than PET".
Researchers from the United States and Britain accidentally engineered an enzyme that eats plastic.
Increasing the volume of plastic that is recycled could significantly cut the amount that finds its way into the sea, which now stands at about a truck load every single minute worldwide.
Though the rise of plastics since the 1960s has led to tons of trash floating around the world's oceans, the discovery brings hope that plastic bottles will soon stop their accumulation in our water.
Douglas Kell, a professor of bio-analytical science at Manchester University, said further rounds of work "should be expected to improve the enzyme yet further".
Prof McGeehan, director of the Institute of Biological and Biomedical Sciences in the School of Biological Sciences at Portsmouth, said: "We can all play a significant part in dealing with the plastic problem, but the scientific community who ultimately created these "wonder-materials", must now use all the technology at their disposal to develop real solutions".
The research team also included scientists from the US National Renewable Energy Laboratory. But instead of the mutated PETase proving more ineffective at degrading PET, the team found the opposite, that it actually performed better.
Miami will need to focus on protecting the ball against some very stingy Philadelphia defenders in the next game. He averaged 22.9 points, 10.9 rebounds, 3.1 assists and 1.76 blocks in 63 games this season.
The agency arrested Sengar, the prime accused in the case, last night after 16 hours of questioning at its office in Lucknow . The police officer then advised the criminal that if he wanted to save himself, he should "manage" local BJP leaders.
However, the damage has been done and people are taking action by protesting in front of the Center City Starbucks in Philly. Two black men had been arrested waiting for their friend at a local Starbucks for a business meeting.

The South Africa 2013 African Cup of Nations winners still trailed Tunisia, Senegal, Congo DR, Morocco and Egypt on the continent. Nigeria's group opponents, Argentina , Croatia and Iceland were ranked 5th, 18th and 22nd respectively.
The U.S., Great Britain and France fired 105 missiles at three sites in Syria early Saturday morning local time, Lt. Trump said he was prepared to sustain the response until the Assad government stopped its use of chemical weapons.
The protests, planned to last six weeks, are calling for Palestinian refugees to return to their former homes, now inside Israel. More than 30 Palestinians have been killed by Israeli gunfire since the start of "Flag Friday" demonstrations two weeks ago.
One site hit by the barrage of missiles was the Bazrah Research Center, a scientific research center on the outskirts of Damascus. The site west of the city of Homs was an alleged underground chemical weapons storage facility, doubling as a command post.
