the same trends in sugar yields from hot water pretreated samples
both with and without disk milling. Samples treated with HW at
180 C for 4 min released the largest amount of oligomeric sugars
(glucooligosaccharide (GOS) of 2.70% and XOS of 9.33%) (Table 3).
As a result, fewer inhibitors were formed, and the highest glucose
and xylose yields were achieved after hydrolysis. Even though HW
at 180 C for 8 min was the most effective condition to deconstruct
biomass structure and resulted in high amount xylose release, relatively
high amounts of inhibitors were generated, which negatively
impacted sugar yields. In particular, sugar yields were
decreased from samples in which furfural was detected (HW at
180 C for 8 min and HW at 200 C for 4 min)
