摘要： Mechanical milling of biomass as a pretreatment to render the biomass readily saccharifiable requires high energy input. Preceding mechanical milling by treatment with anhydrous ammonia was found to greatly reduce the energy requirement for fine milling, providing a more economical pretreatment process for commercial use.

摘要： Methods for treating biomass for release of fermentable sugars with an improved inhibitor profile are provided. Specifically, a hydrolysate comprising fermentable sugars with an improved inhibitor profile is obtained by saccharification of a reaction product obtained by pretreating biomass with ammonia under suitable reaction conditions. The pretreated biomass reaction product has an acetamide to acetate molar ratio greater than about 1 and an acetyl conversion of greater than 60%. The acetamide to acetate molar ratio is maintained greater than about 1 throughout saccharification. The hydrolysate may be fermented to a target compound.
