As early as 2018, scientists from Kyoto University of technology in Japan discovered ideonella sakaiensis, a bacterium that has a natural appetite for pet plastics, thus providing a low-cost solution for the common forms of plastic pollution. Now, scientists have designed a new “super enzyme” based on the bacterium sakazakii, which can increase the digestion rate of plastic waste by six times. < / P > < p > in the study of the fungus, scientists found that it mainly works through an enzyme called “petase”. So researchers at the University of Portsmouth and the National Renewable Energy Laboratory (NREL) designed a new enzyme in the laboratory that breaks down plastics about 20% faster than before. Now, the same team has successfully combined it with its partner enzyme, mhetase, to further speed up digestion. < / P > < p > scientists first studied the atomic structure of enzymes using a synchrotron, which uses an X-ray beam 10 billion times brighter than the sun. The team was able to connect the two enzymes in this way. By simply combining the two enzymes, the digestion rate of plastics is doubled, but after the special connection between them is engineered, a super enzyme & quot; is produced, which increases the degradation rate of plastics three times. Professor John mckihan of the University of Portsmouth said: “our first experiment showed that they worked very well together, so we decided to try to physically connect them, just as two pea eaters were connected by a rope. We are pleased to see that our new chimeric enzyme is three times faster than the naturally evolved independent enzyme, opening up a new way for further improvement Apple extends AppleCare + purchase period: users can decide within 60 days
