Response surface methodology (RSM) to evaluate moisture effects on corn stover in recovering xylose by DEO hydrolysis

► Response surface methodology (RSM), based on a 22 full factorial design, evaluated the corn stover moisture effects in recovering xylose by DEO acid hydrolysis. ► The mathematical statistical model, showed that xylose recovery increases during DEO corn stover acid hydrolysis as the corn stover moisture level increases. ► This observation could be important during the harvesting of corn before it is fully dried in the field.
