While analysing the molecular structure of an existing enzyme, scientists accidentally create a powerful new version.
"This unanticipated discovery suggests that there is room to further improve these enzymes, moving us closer to a recycling solution for the ever-growing mountain of discarded plastics". Little of this is recycled, which means we are polluting our environment with materials that take centuries to degrade, much of which washes out into the ocean where it breaks into tiny pieces that are almost impossible to track, let alone clean up.
"And now that we've shown this, it's time to apply the tools of protein engineering and evolution to continue to improve it".
NREL is the U.S. Department of Energy's primary national laboratory for renewable energy and energy efficiency research and development. The team used the Diamond Light Source, near Oxford, UK, an intense beam of X-rays that is 10bn times brighter than the sun and can reveal individual atoms.
Not that PETase is a slouch - as PET by itself takes centuries to naturally break down, and the enzyme enables the bacteria to shorten that to just a matter of days. But if that hunger happens to be for the plastic used to make single-use bottles - something that doesn't generally degrade in nature and is basically the scourge of modern humanity - I'd say break out the champagne and cigars.
In addition to digesting PET, the new enzyme was also capable of degrading polyethylene furandicarboxylate (PEF), a bio-based form of plastic being hailed as a replacement for glass beer bottles.
Other types of plastic could be broken down by bacteria currently evolving in the environment, McGeehansaid: "People are now searching vigorously for those".
"Enzymes are non-toxic, biodegradable and can be produced in large amounts by microorganisms", said Oliver Jones, a expert in analytical chemistry at Royal Melbourne Institute of Technology University.
National Geographic will commit $10 million (£7m) and bring its scientific expertise, grants and media to support the activities of Sky Ocean Ventures, which seeks out investment opportunities in businesses that can help solve the ocean plastic crisis.
Prof Adisa Azapagic, at the University of Manchester in the United Kingdom, agreed the enzyme could be useful but added: "A full life-cycle assessment would be needed to ensure the technology does not solve one environmental problem - waste - at the expense of others, including additional greenhouse gas emissions".
"What actually turned out was we improved the enzyme, which was a bit of a shock".
Both Cohen and Broidy were appointed to the post of Republican National Convention chairman in April 2017. Both agreements had separate side letters that listed the real names of the parties, this person said.
Manchester City are in the league of their own this season - having won 27 of their 32 round of matches already played this term. The Spain playmaker has eight goals and 11 assists to his name in a City team which has dominated the competition this year.
Bush further ensured family support to Lady Barbara and expressed his gratitude towards those offering prayers for her. Most recently, she was admitted to Houston Methodist Hospital on Good Friday suffering from shortness of breath.
Wang, who will be in Tokyo until Tuesday, will also participate in the fourth China-Japan High-level Economic Dialogue. Economy Minister Toshimitsu Motegi is likely to lead the Japanese delegation, with his counterpart likely to be U.S.
The French presidency issued a video on Twitter showing what it said were Rafale warplanes taking off as part of the intervention. The statement also accused Syria of providing military bases for Iran, putting its "territory, forces and leadership in danger".
Asked whether Israel helped choose targets, the official, who spoke on condition of anonymity, said: "Not to my knowledge". African asylum seekers and Israeli activists protest in central Jerusalem, against their deportation, on April 4, 2018.
Lekhi said: "In Kathua rape case, a fair probe is going on and strictest action has been demanded against the culprits". He appealed the party leaders to observe fast in their respective constituencies along with a large number of people.
Apartheid authorities sought to denigrate her with bitter and twisted lies, but still she rose. "Yet, throughout, she endured". She was a witness to the truths and horrors of our nation, not only because of her own hardships but because of her courage.
Hydro One said it has crews ready to respond to outages 24/7, and additional resources are on standby this weekend. It says the wintry weather is expected to continue into Sunday, and will likely lead to unsafe driving conditions.
The task force will also review how the decline in mail volume is affecting the USPS, along with its work force and operations. A White House official said the presidential order was meant to come up with solutions to the problems at the Postal Service.
WPP CEO quits after three decades building ad empire
While the timing was sudden (and perhaps calculated to limit immediate PR damage), his exit is not all that surprising. The investigation into Sorrell has now concluded, WPP said, reiterating that the amounts weren't material.
Sixers' Joel Embiid to remain sidelined for Game 2
Embiid, 24, was named to his first All-Star team this season and leads the Sixers in points (22.9) and rebounds (11) per game. They have also won nine straight games without their best player, dating back to the regular season.
