Napiegrass (Pennisetum purpureum Schumach), rice straw, silvergrass, and bamboo were treated with a low-moisture anhydrous ammonia (LMAA) pretreatment by adding an equal weight of water and keeping it under atmospheric ammonia gas at room temperature for one to four weeks. After the removal of ammonia and washing with water, a saccharification (SA) was conducted for the LMAA-pretreated napiergrass (10.0g) in a buffer solution (60mL) using a Acromozyme cellulase (1.0g). From the results of SA, the LMAA-pretreatment for four weeks was suitable pretreatment. In the case of LMAA-pretreated napiergrass for four weeks, glucose and xylose yields were 83% and 44% yields, respectively. In SEM analysis of these lignocelluloses, many notches were observed in the fiber of the LMAA-pretreated napiergrass and rice straw.
