  1. a The composition of insoluble solids are based on oven-dry weight. b Values are expressed as averages of three replicate samples. Coefficient of variation (CV) is below 2.1 %. c Values were calculated based on the total recovery, composition of alkaline pretreated, as well as that of raw corn stover. d Center point of the central composite design.
