Wheat straw was successfully fermented to ethanol by Fusarium oxysporum F3 in a one-step process. Cellulose crystallinity was found to be a major factor in the bioconversion process. Ethanol yields increased linearly with decreasing crystallinity index. Approximately 80% of straw carbohydrates were converted directly to ethanol with a yield of 0.28 g ethanol/g-1 of straw when the crystallinity index was reduced to 23.6%.Wheat straw was successfully fermented to ethanol by Fusarium oxysporum F3 in a one-step process.
