The fungus called Gliocladium roseum can convert cellulose, which is the polysaccharide used by plants in their cell walls, into hydrocarbons that resemble diesel used in cars and trucks.

Cellulose is the most abundant organic molecule on earth! Read more about it here.

Cellulose is also a major component of paper, which could be used as a food source for the fungus.

Usually, biofuel production involves converting cellulose into sugars for microorganisms to feed on, but using G. roseum, the cellulose can be used directly.
