Enhanced enzymatic sugar production from corn stover by combination of water extraction and glycerol-assisted instant catapult steam explosion

Abstract

•	Glycerol-assisted ICSE of corn stover improved enzymatic glucose production.
•	Water extraction prior to ICSE further enhanced sugar production.
•	Enzymatic hydrolysis was not affected by glycerol from glycerol-assisted ICSE.
•	Sequential water extraction and ICSE led to a high glucan digestibility of 89.7%.
•	Glycerol likely had a multiple role in ICSE and enzymatic hydrolysis.

Keywords
