Optimizing Harvest Of Corn Stover Fractions Based On Overall Sugar Yields Following Ammonia Fiber Expansion Pretreatment And Enzymatic Hydrolysis, Rebecca G. Ong, Shishir Ps Chundawat, Venkatesh Balan, Bruce E. Dale

Background: Corn stover composition changes considerably throughout the growing season and also  varies  between  the  various  fractions  of  the  plant.  These  differences  can  impact  optimal pretreatment  conditions,  enzymatic  digestibility  and  maximum  achievable  sugar  yields  in  the process of converting lignocellulosics to ethanol. The goal of this project was to determine which combination of corn stover fractions provides the most benefit to the biorefinery in terms of sugaryields and to determine the preferential order in which fractions should be harvested. Ammoniafiber expansion (AFEX) pretreatment, followed by enzymatic hydrolysis, was performed on early and late harvest corn stover fractions (stem, leaf, husk …
