The world's oceans are filled with plastics more than 5 million pieces of it are floating around being eaten by aquatic animals. Every year more than 100,000 marine animals and seabirds are killed by plastic waste. The accidental discovery of this natural enzyme was made while examining the structure of a bacterium found in the waste dump in Japan.A crew of Japanese researchers described that this bacteria named as  Ideonella Sakaiensis  could break the molecular bonds of one of the world's most used plastics Polyethylene terephthalate. The aim of the researchers was to determine how this works and what's the structure of it, but they ended up creating an artificial one better than the natural one. Ideonella Sakaiensis was found outside of a bottle recycling plant, the pathogen appears to have evolved a pair of enzymes.It uses these break down a PET. PETas e works by reversing the manufacturing process by reducing polyesters  back to their building blocks .Ideone
