  • AMMONIA PRETREATMENT OF BIOMASS FOR IMPROVED INHIBITOR PROFILE
    Publication number: 20110250646
    Abstract: 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.

  • METHODS TO IMPROVE MONOMERIC SUGAR RELEASE FROM LIGNOCELLULOSIC BIOMASS FOLLOWING ALKALINE PRETREATMENT
    Publication number: 20110250645
    Abstract: A method is provided for improving the release of monomeric sugars from alkaline pretreated biomass. The method includes further processing of pretreated biomass and addition of a chemical to the saccharification reaction, which together provides for unexpected release of high levels of monomeric sugars that may be fermented to target products.
