Overall cellulose conversion
Overall cellulose conversion was calculated taking account the cellulose loss in the pretreatment, alkaline delignification and enzymatic hydrolysis. The purpose of this overall yield is to verify the fraction of the cellulose from raw sugarcane straw recovered as glucose in the hydrolysate.According to Table 5, the highest overall cellulose conversion was obtained for sugarcane straw pretreated at highesttemperature (190◦C) and time (10 min). The addition of alkaline delignification in the process provided reduction of overall
