Enzymatic digestion rate of a pure cellulose and b green liquor-pretreated poplar (GL-P) after adding different dosages of PSS or LS. The enzymatic hydrolysis was conducted in acetate buffer (pH 4.8) and continued for 72 h. The cellulase dosage in a was 6.3 FPU/g-glucan while 13.3 FPU/g-glucan in b. The data of open symbols in b were
