*mass yield calculated on basis of 100 g dry weight raw Miscanthus.
#percent of theoretical yield was calculated on basis of the amount of original glucan or xylan contents in raw Miscanthus.
** The highest or lowest yields of HTPH for the pretreatment of 0 or 35 min.
Glu-glucan, xyl-xylan, lig-lignin.
