Plastic-Degrading Enzyme
Eight million metric tons of plastic waste, including polyethylene terephthalate (PET) bottles, enter the oceans each year, creating huge manmade islands of garbage. Experts estimate that by 2050, there will be as much waste plastic in the ocean by mass as there are fish. A bacterium, Ideonella sakaiensis 201-F6, can...
