After the removal of ammonia and washing with water, a simultaneous saccharification and fermentation (SSF) was conducted for the LMAA-pretreated napiergrass (1.33 g) in a buffer solution (8 mL) using a mixture of a cellulase (80 mg) and a xylanase (53 mg) as well as the cell suspension (0.16 mL) of Saccharomyces cerevisiae. Ethanol and xylose resulted in 91.2% and 62.9% yields, respectively. The SSF process was scaled up using LMAA-pretreated napiergrass (100.0 g) to give ethanol (77.2%) and xylose (52.8%). After the removal of ethanol, the pentose fermentation of the SSF solution (40 mL), which contained 1.00 g of xylose, using cell suspension of Escherichia coli KO11 (70 mL) gave 86.3% yield of ethanol. Total ethanol yield reached 68.9% based on xylan (21.4 wt%) and glucan (39.7 wt%) of the LMAA-pretreated napiergrass.}, pages = {179--185}, title = {Enhancement of Ethanol Production from Napiergrass (Pennisetum purpureum Schumach) by a Low-Moisture Anhydrous Ammonia Pretreatment}, volume = {3}, year = {2013}, yomi = {ヤスダ, マサヒデ and タケオ, ケイスケ and ウト, タクヤ and ユイ, トシフミ and マツモト, トモコ and イシイ, ヤスユキ and オオタ, カズヨシ and タケオ, ケイスケ} }
