With its help, plastics can be turned into smaller parts and go away quickly. Scientistsbelieve that, in the future, it could solve the problem of plastic pollution.The enzyme is able to break__down PET, a form of plastic. PET was first made in the 1940sand is now widely used to make plastic bottles. It can remain in the environment for many yearsand pollute large areas of land and water. So it has always been a headache to deal with the wastefrom PET and other plastics. The researchers made the discovery while examining the structure of a natural enzyme inJapan. They found that the natural enzyme was helping to break down PET plastics. So, theydecided to make small changes to the enzyme by adding some amino acids (氨基酸). It made thenatural enzyme's plasticeating abilities work faster and better.John McGeehan, one of the lead researchers, said, “We've made an improved enzyme. It'sbetter than the natural one. And we are trying to make more improvements to it.” He went on,“The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we areconsidering putting it into wider use.”The team is now trying to make the enzyme break down PET in large quantities(大量地) .“We'll see that the plastic pollution may be stopped with this technology. However, there is still along way to go，” John McGeehan added.第 2 页
