     When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that

eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are

interested in what the bears leave behind; their poop (排泄物). At a recent meeting in Denver, Professor Brown

at the university presented her research showing how panda poop could inspire a new way to obtain energy

from plants, which are a renewable energy source. Usually, plants can be called biomass (有机燃料) when

they are used as an energy source.

     Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists

something about breaking down biomass. Pandas - or at least the bacteria in their stomachs - are very good at

getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda

has only one stomach. Bamboo comes in, and poop goes out.

     Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two

pandas. Ya Ya and Le Le living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break

down biomass, including one that had never been found in pandas. Brown says that because the poop contains

bacteria that break down biomass, it could also be used to break down other types of biomass.

     Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and

then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn

biomass - like grass or other plants - into fuel.

     Brown says she doesn't mind handling panda poop."It's probably the most pleasant material to work with,"

she says,"My colleagues and I have been working with other poop for a long time, and we can assure you it

has a fairly pleasant smell associated with it."
