Theoretical integration process yield of fermentation products if individual yields in this study were extrapolated to 1 dry tonne of corn stover (CS). The highest overall yields exceeding 200 kg of product per tonne were achieved for CS DDR (80/120/0.005), CS DDR (100/120/0.005), and CS DDR (100/120,0.015). The theoretical maximum overall product yield from corn stover is 300 kg. X/Y/Z represents NaOH conc (g/kg)/residence time (min)/disc-refining gap (in.)
