An endophytic Hypoxylon sp. (CI-4) known to produce volatiles having potential value as fuels was initially evaluated. Rapid growth was obtained on a medium containing the degraded cellulose as the sole carbon source and the volatile compounds produced were largely the same as those produced from a conventional dextrose/starch diet. A second Hypoxylon sp. (BS15) was also characterized and shown to be phylogenetically divergent from any other named species. The degraded cellulose medium supports growth of BS15 and approximately the same quantity of volatile compounds were produced as from conventional diets. Although the major products from BS15 grown on degraded cellulose were identical to those from dextrose, minor products differed. Extraction of volatiles from growth media was achieved using solid-phase extraction in order to reduce solvent waste and more efficiently retain compounds having low vapor pressures. A comparison to more conventional liquid-liquid extraction demonstrates that, for CI-4, both methods gave similar results. Solid-phase extraction of BS15 retained a significantly larger variety of volatile compounds than liquid-liquid extraction. These advances positon the coupling of solvent-free cellulose conversion and endophyte metabolism as a viable strategy for the production of important hydrocarbons.} }
