Panda Poo Yields Key To Cheaper Biofuels 113
An anonymous reader writes "A new study unveiled at the American Chemical Society points to panda poop as a source of remarkably efficient enzyme-producing bacteria that are able to break down plant materials for cheaper and more efficient biofuel production. Inspired by the giant panda's voracious appetite for bamboo, scientists began to study the fecal matter of giant pandas at the Memphis Zoo. A year of samples indicated that the pandas have a unique ability to convert lignocellulose from plant matter into energy. In fact, gut bacteria of a giant panda can convert 95 percent of the plant's biomass into simple sugars."

I think his point is that if the enzymes are so efficient, then what does the panda do with all that energy the enzymes produce?
Judging by the summary "shit it out" is one possible answer I suppose.

Agreed, I think the speed with which bamboo grows is really key here, and if this offers a better way of harvesting it as a biofuel then great.
For those who aren't aware, bamboo has very high oil content and, given the right conditions, some species can grow literally upto a metre per day. That's much better than many other plant species harvested for biofuel!
Re: Up to a metre per day. (Score:5, Informative)
some species can grow literally upto a metre per day
While that's accurate, I think it would be misleading to allow it to stand without comment. Bamboo gather energy during the year and store it in their rhizomes. Then they use that energy during the growing season to sprout new shoots. It's these new shoots which may grow that quickly, but only during that season. Any culms from previous years are stuck at whatever height they grew to during their growing year.
What I've said is true of the seven species that I own. Of course there are hundreds of species, so others may exhibit other habits.
I don't own any panda, so I don't have any personal knowledge of their habits, but my understanding is that they eat bamboo leaves. It's the culms that may grow so quickly.

The conservatives are partially correct. In the habitats we offer them Pandas are completely incapable of surviving without human assistance. They require insanely huge bamboo forests to sustain their pathetically wasteful lifestyle and slow reproduction.
But humans at least reduced those huge forests down to a point where they couldn't sustain a panda population, so IMO it's our responsibility to to keep them from going extinct.
