摘要：

Empty fruit bunches were received from Teck Guan, Malaysia and were pretreated and enzymatically hydrolyzed to determine the possible sugar recovery from the biomass. Several different conditions were explored in a screening study. Temperature ranged from 100 degrees C to 150 degrees C, time ranged from 30 to 90 min, and acid loading ranged from 0 to 1.3% weight acid/weight liquid. The material was then enzymatically hydrolyzed at three different enzyme loadings 1.67%, 3.33%, and 6.66% (g enzyme/g glucan x 100) and total sugar recovery was calculated for both pretreatment and enzymatic hydrolysis. Best pretreatment conditions yielded 81.4% recovery of hydrolyzed xylan. Best glucan conversions in enzymatic hydrolysis were 74.8%. These conversions and recoveries make empty fruit bunches a good potential feedstock for cellulosic ethanol. (C) 2016 Elsevier B.V. All rights reserved.
