Effects of ATSE pretreatment under different conditions on glucan recovery (a), xylan recovery (b) and delignification (c). Recoveryglucan/xylan (%) = Mglucan/xylan of pretreated biomass/Mglucan/xylan of original biomass. Lignin reduction (%) = 1 – Mlignin of pretreated biomass/Mlignin of original biomass. M is mass of sugar/lignin.
