Description: Development work has been underway for pre-extraction of multiple high-value products from flax shive, an agricultural byproduct of flax straw processing for fibre. Sequential flax shive extractions leave behind cellulosic residuals that could represent a low-cost feedstock for further fermentation to produce energy products, notably ethanol and hydrogen. To test this possibility, samples of flax shive after varying pretreatment extractions were tested as fermentation substrates for the microbe Clostridium thermocellum. The results, representing a two-by-three analysis of variance (ANOVA), showed that pretreatment using sodium ethoxide in anhydrous ethanol and/or aqueous sodium hydroxide had no effect on subsequent ethanol yield. Yields for all flax shive fermentations, including use of untreated flax shive, were not statistically different. F-statistics for the two main effects of pretreatment and use of alkaline reagent, and their interaction were too low. The mean ethanol yield was 76.5
