考试真题

But she expects using the chemical in some kind of industrial process-not simply "millions of worms thrown on top of the plastic".

Is it an enzyme produced by the worm itself or by its gut microbes?

Jennifer Debruyn, a microbiologist at the university of tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene.

Researchers in spain and england recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics.

So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.

The team left 100 wax worms on a commercial polyethylene shopping bag 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 and applied it to plastic films.
