The fungus produced the most hydrocarbons on a diet of oatmeal but also created them by eating wheat straw or crop residues from harvested corn. Fungi have been of interest for about a decade within biofuels production sector as the key producer of enzymes necessary for converting biomass to sugars. Some researchers have further shown that fungi could create hydrocarbons, but the research was limited to a specific fungus living within a specific tree in the rainforest, and the actual hydrocarbon concentrations were not reported.
