In 2008, MSU scientists discovered a tiny fungus hiding inside a rainforest tree that naturally produced diesel-like fuel

In 2008, one of the most unexpected discoveries came from deep inside the South American rainforest. Researchers identified a microscopic fungus living quietly within the tissues of a tree that produced a mixture of hydrocarbons strikingly similar to those found in diesel fuel. The remarkable organism, later nicknamed the "diesel tree fungus", raised the possibility that future biofuels might one day be produced by microbes rather than oil wells. Although the discovery did not replace conventional diesel overnight, it opened an entirely new direction in biofuel research and demonstrated how nature can sometimes solve problems in surprising ways.How a microscopic rainforest fungus turned out to produce diesel-like hydrocarbonsThe breakthrough came when researchers from Montana State University studied microorganisms living inside the Ulmo tree (Eucryphia cordifolia) in the temperate rainforests of Patagonia in Chile.Among the organisms they isolated was a previously unknown fungus named Gliocladium roseum.
