Panda Poop Could be the Key to Cheap and Efficient Biofuel Production

Giant Pandas are well-loved for their distinctive appearance and sedentary nature. Now they will receive even greater adoration and attention for their bowel-based  contribution to the development of a clean energy future. In a national meeting at the American Chemical Society , researchers presented a study identifying panda poop as a source of enzyme-producing bacteria that breaks down plant materials in a way that is useful for biofuel production.
Corn-based biofuel production has reached 13 million barrels per year, but processing land and energy-intensive food crops such as corn, soybeans, and sugar is costly and often uses environmentally-damaging chemicals  or harsh acids. Enzymes are known to perform the same function, but often take more time and have trouble breaking down a majority of the agricultural waste (stalks and husks of plants, wood chips, switchgrass, and corn stover ) that also acts as raw material for the biofuels industry. Producing biofuel from this cellulosic-rich biomass is necessary if our aim is to make biofuels an eco-friendly and cost competitive alternative to gasoline.
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. This is a marked improvement upon bark beetles , termites, and the ruminant stomachs of cattle, which have also contain biomass conversion capable enzymes.
Instead of harvesting the enzyme-rich poop  from bamboo forest floors in the mountains of China, the next step will be to sequence the specific gene(s) responsible for the highly-active enzyme. Once isolated, the gene(s) will be put into a yeast and the yeast culture will produce the enzymes capable of digesting and converting biomass on a commercial scale.
This is good news for the the commercial biofuel industry, which is expected to advance rapidly as a result of President Obama ‘s recent announcement  that the US Department of Agriculture, Energy, and Navy will invest $510 million in biofuel production by 2014. This discovery gives biofuels another big boost, but it should also serve as a reminder of the importance of biodiversity and the role it plays in innovating technologies, medicines, and materials.
