Cellulose conversions of raw and pretreated A. donax. by enzymatic saccharification. Cellulose conversions expressed as percentage of the theoretical glucose in pretreated samples. a Effect of solid acid reaction time (0.5, 1.0, and 1.5 h) on enzymatic hydrolysis, b Effect of low pretreatment temperature (90, 100, and 110 °C) on enzymatic hydrolysis, and c effect of high pretreatment temperature (130, 140, and 150 °C) on enzymatic hydrolysis. Error bars indicate standard deviation of triplicate determinations. Sample code with definition is in Table 1
