Plastic-Eating Worms
(P1) Humans produce morethan 300 million metric tons of plastic every year. Almost half of that windsup in landfills(垃圾填埋场), and up to 12 millionmetric tons pollute the oceans. So far there is no sustainable way to get ridof it, but a new study suggests an answer may lie in the stomachs of somehungry worms.
(P2) Researchers in Spainand England recently found that the worms of the greater wax moth can breakdown polyethylene, which accounts for 40% of plastics. The team left 100 waxworms on a commercial polyethylene shopping bag for 12 hours, and the wormsconsumed and broke down about 92 milligrams, or almost 3% of it. To confirmthat 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 thefilms had lost 13% of their mass—apparently broken down by enzymes(酶) from the worms' stomachs. Theirfindings were published earlier this year in Current Biology in 2017.
(P3) Federica Bertocchini, co-authorof the study, says the worms’ ability to break down their everyday food—beeswax—alsoallows them to break down plastic. “Wax is a complex mixture, but the basicbond in polyethylene, the carbon-carbon bond, is there as well,” she explains.“The wax worm evolved a method to break this bond.”
(P4) Jennifer DeBruyn, amicrobiologist at the University of Tennessee, who was not involved in thestudy, says it is not surprising that such worms can break down polyethylene.But compared with previous studies, she finds the speed of breaking down inthis one exciting. The next step, DeBruyn says, will be to identify the causeof the breakdown. Is it an enzyme produced by the worm itself or by its gutmicrobes(肠道微生物)?
(P5) Bertocchini agrees andhopes her team's findings might one day help employ the enzyme to break downplastics in landfills. But she expects using the chemical in some kind ofindustrial process—not simply “millions of worms thrown on top of the plastic.”
