The future may be panda powered

Study: Panda Poo May Be Coup for Future of Biofuels | Climate Central

Good to see innovative uses for pandas:

Brown’s team has found more than 40 different microbes living in the guts of giant pandas at the Memphis Zoo that could help decompose the corn cobs and other tough plant materials so it can be more easily and efficiently processed to make ethanol.

The study is using the feces from giant pandas Ya Ya and Le Le. Pandas, which have a short digestive tract, feast on a diet of tough bamboo. Bacteria with extremely potent enzymes break down the woody bamboo efficiently and quickly.

“The time from eating to defecation is comparatively short in the panda, so their microbes have to be very efficient to get nutritional value out of the bamboo,” Brown said. “And efficiency is key when it comes to biofuel production — that’s why we focused on the microbes in the giant panda.”

Brown’s team found the specific bacteria that break down lignocellulose into simple sugars, which can be fermented into bioethanol, and they found other bacteria that can transform those sugars into oils and fats for biodiesel production.

The microbes in pandas’ guts are accessible via their feces and can easily be cultured, Brown said.
