Giant reed (Arundo donax L.), a perennial, herbaceous crop of Poaceae family, offers good potential as lignocellulosic feedstock for second generation bioethanol production due to its high productivity and carbohydrate composition. In a previous study we performed the first attempt at dilute-oxalic acid (OA) pretreatment of giant reed. The effect of temperature (170-190 °C), acid loading (2-10% w/w) and reaction time (15-40 min) were treated as a single parameter, Combined Severity (CS). In the present...
