Pretreatment of corn stover for sugar production with switchgrass-derived black liquor

BIORESOURCE TECHNOLOGY, 111, 255–260.

By: J. Xu n, X. Zhang n & J. Cheng n

author keywords: Alkaline pretreatment; Black liquor; Corn stover; Sodium hydroxide; Switchgrass
MeSH headings : Biomass; Carbohydrates / biosynthesis; Hydrolysis; Lignin / metabolism; Poaceae / metabolism; Zea mays / metabolism
TL;DR: Results showed that, because of the high pH and the appreciable amount of carbohydrates in the black liquor, sugar production during enzymatic hydrolysis of corn stover pretreatment with black liquor was comparable to that of biomass pretreated with 1% NaOH. (via Semantic Scholar)
