The team left 100 wax worms on a commercial polyethylene shopping b
3、ag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste( 糊状物 ) and applied it to plastic films. 14 hours later the films had
4、lost 13% of their mass apparently broken down by enzymes ( 酶) from the worms stomachs. Their findings were published in Current Biology in 2017.

5、 is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, she explains, The wax worm evolved a method or system to break this bond.

6、ng that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes( 肠 道微生物 )? Be
7、rtocchini agrees and hopes her teams findings might one day help employ the enzyme to break down plastics in landfills.
