Glucose production rates (GPRs) during 4-h enzymatic hydrolysis of lignocellulose substrates. a Reed canary grass; and b Pine bark. Enzymatic hydrolysis experiments were performed with either non-treated or H2SO4-treated (SF 4.1), or (S)IL-treated lignocelluloses. (S)IL treatments were performed at (A) SF 2.5 (B) SF 3.7 and (C) SF 4.1
