A yield of 118.1 mg TRS/g of biomass has been obtained for the
same material pretreated with 4 wt.% NaOH (for 2 h at 55 C) after
hydrolysis for 45 h at 50 C [37]. Yields of total reducing sugars as
high as 810.9 mg TRS/g of pretreated biomass, for switchgrass pretreated
with 2 wt.% NaOH (for 60 min at 121 C) after hydrolysis
for 72 h at 55 C, and 636.9 mg TRS/g pretreated biomass, for
switchgrass pretreated with microwaves (with 2 wt.% NaOH for
10 min at 1250 W) after hydrolysis for 72 h at 55 C, have been reported
[36].
