Rainforest Fungus Naturally Synthesizes Diesel

A fungus that lives inside trees in the Patagonian rain forest naturally makes a mix of hydrocarbons that bears a striking resemblance to diesel, biologists announced today. And the fungus can grow on cellulose, a major component of tree trunks, blades of grass and stalks that is the most abundant carbon-based plant material on Earth.

"When we looked at the gas analysis, I was flabbergasted," said Gary Strobel, a plant scientist at Montana State University, and the lead author of a paper in Microbiology describing the find. "We were looking at the essence of diesel fuel."

While genetic engineers have been trying a variety of techniques and genes to get microbes to create fuel out of sugars and starches, almost all commercial biofuel production uses the century-old dry mill grain process. Ethanol plants ferment corn ears into alcohol, which is simple, but wastes the vast majority of the biomatter of the corn plant.
