Title: Impact of Drought on Chemical Composition and Sugar Yields From Dilute-Acid Pretreatment and Enzymatic Hydrolysis of Miscanthus, a Tall Fescue Mixture, and Switchgrass

Abstract

Environmental factors, like drought, during plant growth are a source of variation that can impact biomass quality entering a bioconversion process. Drought has been linked to lower structural sugars for lignocellulosic biomass. These changes could have economic impacts, particularly when compounded with losses in dry biomass yield; however, the effects on conversion efficiency are not completely understood. The objective of this study was to determine how drought impacts biomass composition and sugar yields from dilute-acid pretreatment (DAPT) and enzymatic hydrolysis (EH). Miscanthus, a tall fescue mixture, and switchgrass from Nebraska, Missouri, and Oklahoma, respectively, were included. Samples were grown in a year without drought (2010) and a year with extreme drought (2012). Non-structural glucose and proline were significantly greater in 2012 compared with 2010 for Miscanthus, indicating drought stress. Only proline was greater in 2012 for the tall fescue mixture. Structural glucan and xylan were significantly lower in 2012 for Miscanthus and the tall fescue mixture. Reactivity and sugar yields from DAPT and EH were significantly greater in 2012 compared with 2010 for Miscanthus, indicating that, even if structural sugars decrease during drought, sugar yields and reactivity may increase. For the tall fescue mixture, only xylan yield was greater aftermore » drought. No differences between 2010 and 2012 were observed for switchgrass composition or reactivity, except for higher total glucose yield in 2010. Drought impacts appear feedstock specific, likely because of species’ specific tolerance drought. In conclusion, as drought occurrence and severity have increased, understanding drought impacts is necessary for bioenergy industry growth.« less
