樹上柴油,己經出現。
Disesel oil is discovered to be a product of fungus living in tree.

Disesel oil is discovered to be a product of fungus living in tree.

A month ago, after analysis of mixture produced by fungus Gliocladium roseu, some hydrocarbons remarkably similiar to diesel oil is found. Gliocladium Roseu is a fungus living in ulmo tree in Patagonia. this discovery is made by The Us researchers with its detail being published in the this year November issue of Microbiology magazine.

The 'myco-diesel' fungus Gliocladium roseum, which grows inside the ulmo tree in northern Patagonia

A tree fungus could provide green fuel that can be pumped directly into vehicle tanks, US scientists say. The organism, found in the Patagonian rainforest, naturally produces a mixture of chemicals that is remarkably similar to diesel.

The fungus, called Gliocladium roseum and discovered growing inside the ulmo tree (Eucryphia cordifolia) in northern Patagonia, produces a range of hydrocarbon molecules that are virtually identical to the fuel-grade compounds in existing fossil fuels.

Many simple organisms, such as algae, are known to make chemicals that are similar to the hydrocarbons present in transport fuel but, according to Strobel, none produce the explosive high energy density found in this fungus.

It was said that the chemical mixture produced could be used in a modern diesel engine without any modification.

Another advantage of the fungus is its ability to eat up cellulose, the compound that makes up much of the organic waste that is currently discarded, such as stalks and sawdust. Converting this plant waste into fuels is an important goal for the biofuel industry, which currently uses food crops such as corn.
